I agree. There is no point in hiring anyone into a technical-only role anymore. It's very valuable (and probably always will be) to be something-and-technical: a specialist in the target field who also understands how computers and software work. But not "just" technical, these are already completely obsolete and all of them who still have jobs, do so simply because of institutional inertia, connections, and companies being awash with money. Which is not to say that this is not a sustainable state of affairs - it may very well be so forever.
Do you realize that there is software out there that are not simple React apps? The models are clearly advanced but I think the world is a lot more complex than you seem to think.
I have basically vibe-coded a guidance system for air defence interceptors in 6 weeks. It works. Took getting my hands dirty with soldering and some mechanical work to test, but Cursor was guiding me on even that. And i started with understanding concepts like "what is a quaternion" and "why doesn't an infrared camera have a concept of exposure time even as it does have a framerate".
I had a "wow it can vibe code a React app" moment 1.5 years ago. AI evolved a lot since.
I admit i had to hire contractors to do designs for 3D printing. I don't know how to outsource it to AI yet, maybe i can't.
