The uncomfortable part of all this is that it is not a technology problem. It is a leadership problem. AI does not make bad executives worse. It gives them a faster way to prove they are bad. The leaders still standing in 2030 will be the ones honest enough to put the rehiring cost in the business case before the ink dries on the layoff letter.
ROFL
There are specialities that can extend his time in the industry, allowing him to build up more of a nest egg before he makes any kind of a jump.
For example, DBAs (database administrators and specialists) will not go away any time soon. Same goes for observability (tracking user behaviour and system errors). Both of those require a sense of “correctness” and intuition that AI hasn’t gotten anywhere near to mastering.
Good luck.
