Man, I'm going to make so much money as a Cybersecurity Consultant!
However, what we are maybe not considering enough is that general AI adoption could and almost certainly will affect the standards for cybersecurity as well. If everyone uses AI and everyone gets used to its quirks and mistakes and is also forgiving about someone else using it since they themselves use it too, the standards for robust and secure systems could decrease to adjust to that. Now, your services as a cybersecurity consultant are no longer in need as much, as whatever company would need them can easily point to all the other companies also caring less and not doing anything about the security issues introduced by the AI that everyone uses. The legal/regulation body would also have to adjust to this, as it is not possible to enforce certain standards if no one can adhere to them.
