      It’s true that AI presents certain security risks, but it’s also important to recognize that it offers significant benefits and can enhance security when used responsibly.

      • Ravi,

        Your answer reminds me of something a politician would say. :-)

        You mentioned “certain security risks“. When it comes to security, there’s no such thing as “acceptable“. You’re either secure or you’re not.

        You also mentioned “significant benefits“. What benefits are these? Convenience? The cost of convenience is often privacy and security. Even before the widespread use of ‘smart devices‘, it was widely known that WiFi devices were susceptible to hacking.

        Yet, the adoption of ‘smart devices‘ and ‘smart homes‘ skyrocketed. Anyone questioning the security of ‘smart‘ technology was often dismissed as anti-progress. It’s only recently that tech journals and blogs have started highlighting the vulnerabilities of ‘smart devices‘.

        Similarly, AI is now the new shiny toy, and everyone is eager to jump on the bandwagon. Few are raising concerns, and unfortunately, those who do are often dismissed as Luddites.

        You mentioned AI can “enhance security when used responsibly“. However, if something poses a security risk, how can it possibly “enhance security“? Phrases like “used responsibly” are empty and meaningless.

        Currently, AI is akin to social networks. Despite efforts, platforms like Facebook, Instagram, and Google harvest personal data without adequate consent, which I find unacceptable.

    • @Venkatesh,

      Sorry, it was a mistake. I was referring to ChatGPT. I have corrected the article.

      Thanks for pointing it out!
