I&#x27;m in the same boat; only I&#x27;m creeping up on 50 and have been working with computers since the early 80&#x27;s (TRS-80 Color Computer).  I have worked on most computing systems that you can think of (zOS, HP3000 MPE, Linux, AWS, Ruby on Rails, etc.) and am constantly looking at the next new thing (Rust vs. Go).<p>The problem that I seem to be running into is that I&#x27;m not a super speedy coder who is able to build a full featured Rails app (with tests, DB, front end JS, etc.) in 8 hours.  With age I have definitely slowed down, but I&#x27;ve gained so much experience and knowledge about what will work well and what path you shouldn&#x27;t take.  I guess that experience is really only needed with smaller companies who can&#x27;t afford to make the wrong decision early on.
