Civil will be replaced by AI in 20 years or less, so hang a shingle if you have your stamp and start a small firm doing subcontracts to megafirms while you still can.

Mech should be the same to slightly better at all levels.

The nature of STEM work has also changed dramatically in the past several decades. In engineering, for instance, your job is no longer linked to a company but to a funded project. Long-term employment with a single company has been replaced by a series of de facto temporary positions that can quickly end when a project ends or the market shifts. To be sure, engineers in the 1950s were sometimes laid off during recessions, but they expected to be hired back when the economy picked up. That rarely happens today. And unlike in decades past, employers seldom offer generous education and training benefits to engineers to keep them current, so out-of-work engineers find they quickly become technologically obsolete.
