Whenever anything gets streamlined in our industry (better work process/compiler/editor/language), successful company instead of letting go skilled workers end up branching out into more products and regions. Inventing new industries gets so crazy, we end up leaving things in legacy repos for decades. A complete normalization/standardization for the entire engineering spaces would be both wasteful and unnecessary (what, requiring everyone to know all of the industries and languages before they can get hired?) Even if you get to the point of AI programmers who can replace people, you may run into a incentive problem because AI would have no use of money.
