I think the tech industry is overestimating its value. Because it can code they think it can do anything else, but unlike code a lot of other work can't have a bunch of little bugs and mistakes because you can't open up real life and edit it after the fact. Plus it lacks actual reasoning to solve novel problems.
Hiring an engineer to finetooth comb blueprints for mistakes before construction will take nearly as much time as having an engineer draft them themselves. And they will be smart enough to not do something silly like putting the electrical panel on the back of the shower wall. If you just vibecode some blueprints and start construction without the comb you could lose way more than you saved with something as simple as pouring a support pillar or building a wall 2 inches off and having to tear it out later and rebuild.
