I think you can learn as you go with tech. It depends on where you start. If you are a humble hobbyist with a few projects under his belt then a junior position isn’t too far out of reach.
As long as you pace yourself and are open to learn you can become a senior developer.
I don’t mean this in any way condescendingly or to imply these people are dumb. Often parents/partners are telling them “go get a job”. The process is discussed a lot on HN, Reddit etc, but most people don’t know that job searching is itself a skill in and of its own. They don’t teach that in HS or college.
