The business leaders do not care about this yet. I think a lot of people think we already have more Seniors than we will need in the next 5-10 years.

Also - the definition of Senior will change, and a lot of current Seniors will not transition, while plenty of Juniors that put in a lot of time using code agents will transition.

The bet from various industry leaders appears to be that the current generation of engineers will be the last who will ever need to think about complex systems and engineering, as the AI will just get good enough to do all of that by the time they retire.
