Engineering is about trust. In all other and generally more formalized engineering disciplines, the actual job of an engineer is to provide confidence that something works. Software engineering may employ fewer people because the tools are better and make people much more productive, but until everyone else trusts the computer more, the job will exist.
If the world trusts AI over engineers then the fact that you don’t have a job will be moot.
In civil engineering public works are certified by an engineer; its literally them saying if this fails i am at fault. The public is trusting the engineer to say its safe.
