I'm a 43 yo autodidact + BS EE/CS. Haven't had a problem except for resume gaps when doing side-hustles and unnamed startup consulting for too long, HR at shops raise their eyebrows. When it gets to in-person interviewing, I may have a leg over with ~10 years of neanimorphism, look somewhat between a neohippie artist and an idle trustfunder (definitely neither, LOL!), and (obnoxious bragging here) date college students which might help with youthful-seeming attitude.
Oh and worked on nuclear reactor simulators, infosec research, compilers, industrial mining embedded systems, HPC biomedical informatics, and just about every permutation of AWS/hybrid cloud startup scaling (Prod Eng/SRE). Rust, Haskell, C, Ruby, TS/Elm, and so on.
There's always learning, new approaches, and shifting standards to handle.
The more you know, the more you know that you don't.
Buying into one's own ego / being the office jerk are the biggest enemies in high-productivity tech. Relentlessly resourceful go-givers tend to win out in the long-term as the most valuable employees because the big name celebrity rockstar whatever tends to write checks their hubris can't cash.
