    Beyond the Hype: 6 Counter-Intuitive Truths About Artificial Intelligence

    Artificial Intelligence is dominating conversations about the future. Across every industry, from healthcare to finance, AI is hailed as a revolutionary force promising unprecedented innovation and efficiency. The public imagination is captivated by the potential for intelligent systems to solve complex problems, automate mundane tasks, and unlock new frontiers of creativity.

    Beneath the surface of this technological gold rush, however, lies a set of complex, surprising, and often counter-intuitive realities. The same tools that build are also used to break; the code that automates can also mislead; the systems designed to help can also cause harm. Understanding these nuances is no longer just for developers or policymakers—it is a crucial guide for every citizen, consumer, and business leader navigating the cognitive dissonance of our increasingly AI-driven world.

    This article cuts through the noise. Distilled from recent legal rulings, technical deep-dives, and cybersecurity analyses, here are six impactful truths that dismantle common myths and reveal the technology’s turbulent inner workings.


    1. Your AI Assistant Can Become a Master Manipulator

    While AI is widely celebrated for its ability to enhance productivity, the same technology is being weaponized by cybercriminals to launch social engineering attacks of unprecedented scale and sophistication. The classic techniques of impersonation and manipulation are being supercharged by AI, making fraudulent communications more personalized, grammatically perfect, and dangerously convincing.

    According to cybersecurity experts at CrowdStrike, AI is ideal for collecting and processing vast amounts of personal data, allowing attackers to craft highly targeted phishing and business email compromise (BEC) campaigns. The threat, however, goes far beyond convincing emails. As CrowdStrike notes, “AI tools can now conduct thousands of phone calls simultaneously, each highly personalized to mimic human conversation…” This attack scalability is amplified by the rise of deepfakes. Attackers now require only short audio or video samples of a person to generate remarkably realistic replications of their voice and appearance.

    This makes it incredibly difficult to distinguish genuine content from a manufactured fake, turning a trusted colleague’s voice on a phone call into a potential attack vector. This dual-use nature of AI is a stark reminder that the very tools that amplify innovation are also being used to exploit human trust more effectively than ever before.


    2. Companies Are Legally Liable for Their Chatbots’ Mistakes

    In a 2024 case summarized by law firm Cassels, the airline was found liable for negligent misrepresentation after its website chatbot provided a customer with incorrect information about bereavement fares. The customer, relying on the chatbot’s advice that he could apply for the special fare retroactively, booked a flight at the regular rate. When Air Canada later rejected his refund application based on its official policy, the customer took the matter to British Columbia’s Civil Resolution Tribunal.

    The Tribunal’s reasoning was direct: a chatbot, even an interactive one, is “still just a part of Air Canada’s website.” The company is responsible for all information on its site and cannot claim the bot is a “separate legal entity that is responsible for its own actions.” This case marks a critical collision between emerging AI technology and real-world legal accountability. This ruling signals a crucial shift: as AI becomes the face of the enterprise, accountability for its actions cannot be automated away; it remains fundamentally human.


    3. Some AI Is So Dangerous, It’s Outlawed

    In the global conversation about how to govern artificial intelligence, the European Union has moved beyond regulation and has outright banned certain AI practices deemed too harmful for society. The landmark EU AI Act draws clear ethical red lines, declaring that some applications of AI are fundamentally incompatible with core societal values.

    Based on Article 5 of the Act, the EU’s list of prohibitions is extensive. Among other practices, the following are now outlawed:

    • Behavioral Manipulation: AI systems that use subliminal, manipulative, or deceptive techniques to materially distort a person’s behavior in a way that is likely to cause significant physical, psychological, or financial harm.
    • Exploitation of Vulnerabilities: AI systems that exploit the vulnerabilities of specific groups of people based on their age, disability, or social or economic situation, with the objective of distorting their behavior in a manner that causes significant harm.
    • Social Scoring: AI systems used by either public or private actors for the social scoring of individuals, where that score leads to detrimental or unfavorable treatment in contexts unrelated to where the data was originally collected.
    • Untargeted Facial Scraping: AI systems that create or expand facial recognition databases through the untargeted scraping of facial images from the internet or CCTV footage.

    The significance of this legislation cannot be overstated. It represents a global first in moving from ethical guidelines to legally binding prohibitions. It is a declaration that the goal is not just to manage the risks of technology, but to protect foundational principles of human dignity, freedom, and fairness from certain applications of AI, no matter how advanced they become.


    4. We Tell AI Our Deepest Secrets, and It Remembers Everything

    A profound disconnect exists between our awareness of data privacy risks and our actual behavior when interacting with AI. Despite widespread skepticism about technology, a report from CTTS, Inc. reveals a surprising and risky trend: users are frequently inputting highly sensitive personal information into AI chatbots.

    The statistics paint a stark picture of this over-trust:

    • 37% of users have shared medical details.
    • 29% have disclosed financial information.
    • 27% have entered account numbers or login credentials.

    This behavior is dangerous because many generative AI systems are not digital confessionals; their memory is long and their reach can be wide. These platforms often retain user inputs to train and improve their models over time. Furthermore, as the CTTS report clarifies, some AI platforms also share this data with third-party vendors. This highlights a critical misunderstanding of how these tools function. Users are treating AI chatbots like silent confidantes, when in reality, they are vast, interconnected databases where our most sensitive disclosures risk becoming permanent, searchable records.


    5. AI Bias Can Create a Vicious Feedback Loop

    The problem of bias in artificial intelligence is not just a static issue of flawed training data—it’s an interactive and self-reinforcing cycle that can amplify societal prejudices. A 2023 paper published on arXiv describes this phenomenon as a “vicious bias circle,” where a biased chatbot and a human user can progressively reinforce each other’s skewed perspectives.

    The cycle works like this: a chatbot, trained on biased data, provides a user with a prejudiced response. This response can influence the user’s worldview. The user then continues the conversation with prompts and feedback that, colored by this new influence, confirm and strengthen the chatbot’s original bias. A powerful real-world example of this was Microsoft’s “Tay” chatbot, which was shut down within a day of its 2016 launch after Twitter users taught it to generate inflammatory and offensive speech.

    The researchers behind the arXiv paper emphasize the gravity of this feedback loop, particularly for younger users:

    When people have long-term conversations with biased chatbots, the passed biases can affect their worldviews. This is especially severe for children. The biased worldviews will affect data collection and annotation, model training, and chatbot development. In this way, biases will become more serious, forming a vicious circle…

    This reveals that AI bias is not a one-way street. It’s a dynamic interaction where technology and human psychology can combine to create a downward spiral of misinformation and reinforced prejudice.


    6. “Making Things Up” Is a Known Bug, Not a Glitch

    Behind the confident, authoritative tone of many AI systems lies a surprising degree of unreliability that developers are still struggling to solve. The tendency for AI to “hallucinate”—to generate convincing but entirely false information—is not an occasional glitch but a fundamental challenge.

    A discussion among technical writers on Reddit tasked with building an internal chatbot for their company’s documentation offers a candid look at this struggle. The original poster noted that achieving accuracy was “a lot more complex that we’d expected,” a sentiment echoed by another user who called it an “open problem.” Lacking a perfect solution, many are resorting to a simple warning label. As one user described their company’s approach to launching its new chatbot:

    we just released ours out into the wild with a disclaimer that it can get things wrong and/or make things up.

    This is perhaps the most counter-intuitive truth of all. While we interact with AI systems that project an air of complete certainty, the engineers behind the curtain are grappling with a known and unsolved problem of fabrication. The solution, for now, is not a technical fix but a legal waiver, fundamentally shifting the burden of truth-finding from the supposedly intelligent machine back to the unsuspecting human user.


    Conclusion

    The journey into the age of artificial intelligence is well underway, but the map is far more complex than the glossy brochures suggest. While the potential for AI to drive progress is undeniable, its day-to-day reality is fraught with profound challenges—from its weaponization by malicious actors and its collision with legal accountability to its capacity for perpetuating bias and its foundational unreliability.

    Navigating this new world requires us to move beyond the hype and engage with these inconvenient truths. The critical question is no longer if we will integrate AI into our lives, but how we will command it. How will we, as its creators and users, build the guardrails necessary to ensure this technology serves humanity’s best interests, not just its own emergent logic?

    The Problem

    Before Home Assistant entered the scene, building a smart home was often a frustrating puzzle of fragmentation. You might pick up a smart bulb from one brand, a thermostat from another, and a security camera from a third, only to find each came with its own dedicated app, its own set of rules, and a host of limitations. This made even simple automations clunky and confined to a single ecosystem, meaning true integration felt pretty much impossible. Imagine wanting your lights to smoothly dim when you start a movie, or your doors to automatically lock themselves as you leave the house; without a unified system, these seemingly straightforward desires quickly became a complex and often exasperating task.

    • Juggling a gazillion apps for all your gadgets
    • Devices from different brands refusing to talk to each other
    • Worrying about your privacy with all those cloud services
    • Trying to set up complex automations feels like rocket science
    • Feeling stuck with one brand because everything else won’t work together

  • Too Many Global Administrators?

    Too Many Global Administrators?

    Best Practices for Microsoft Entra ID for managing Global Administrators

    Updated: September 9, 2025


    Why Limit Global Admins?

    Global Admins have full control over Microsoft Entra ID (formerly Azure AD) and all Microsoft services that rely on Entra identities, including Microsoft 365, Intune, and Azure. This makes them high-value targets for attackers.

    Risks of Excessive Global Admins:

    • Increased exposure to credential theft
    • Greater potential for accidental or malicious changes
    • Difficulty in auditing and managing privileged access

    Microsoft’s Recommendations

    Microsoft advises the following best practices for managing privileged roles in Entra ID:

    1. Apply the Principle of Least Privilege
      Assign only the minimum permissions necessary for users to perform their tasks.
    2. Use Privileged Identity Management (PIM)
      Enable just-in-time (JIT) access for Global Admins and other privileged roles.
    3. Enable Multifactor Authentication (MFA)
      Require MFA for all admin accounts to reduce the risk of unauthorized access.
    4. Conduct Regular Access Reviews
      Use Entra’s built-in tools to review and remove unnecessary role assignments.
    5. Create Emergency Access Accounts
      Maintain two cloud-only break-glass accounts with permanent Global Admin rights for emergencies.

    What Is Microsoft Entra Privileged Identity Management (PIM)?

    PIM is a feature of Microsoft Entra ID that allows you to:

    • Assign time-bound or approval-based access to roles
    • Require MFA, justification, or approval before role activation
    • Get notifications and maintain audit logs for all activations
    • Prevent removal of the last active Global Admin

    Using PIM to Manage Global Admin Access

    Instead of assigning Global Admin permanently, make users eligible for the role and require them to activate it only when needed.

    How to Assign Global Admin Using PIM:

    1. Go to Microsoft Entra Admin Center > ID Governance > Privileged Identity Management > Microsoft Entra roles
    2. Select Global Administrator > Add assignments
    3. Choose the user and set the assignment type to Eligible
    4. Configure activation settings:
      • Require MFA
      • Set activation duration (e.g., 4 hours)
      • Require approval and justification
    5. Save and monitor usage via audit logs

    Additional Security Enhancements

    • Use Role-Assignable Groups: Assign roles to groups instead of individuals for easier management.
    • Implement Conditional Access Policies: Require phishing-resistant MFA or passkeys for role activation.
    • Monitor with Identity Secure Score: Use Microsoft Entra’s recommendations to continuously improve your security posture.

    Summary

    Limiting the number of active Global Admins and using Microsoft Entra PIM is essential for securing your identity infrastructure. By following Microsoft’s best practices, you can:

    • Reduce risk
    • Improve compliance
    • Maintain operational control
