> In general there is an understanding that someone getting paid can focus and do it full time and are expected to be better than someone who does it as a hobby.

For something like flying airplanes, I think this is obviously true: nobody can afford to spend the required hours doing it unless somebody else is paying for the airplane, and the only way that happens is if that person is your employer. A lot of things are like that.

But programming is very different, it requires almost no resources to practice except your time. You can sit at home in your pajamas with $1K worth of hardware and keep yourself busy for a lifetime through open source. Of course, you can also spend a lifetime building useless sandcastles while telling yourself you're a genius: you have to find ways to hold yourself accountable to grow.

I've been fortunate to get paid to work on some interesting things... but the work I do for fun is, on average, ~100x more challenging and interesting than the work I'm paid to do. I would be a much much less capable programmer if I'd only done work I was paid to do for the past decade.

I wouldn't go so far as to say "amateurs are better than professionals", but I think the skill level of the two groups is much more blurred in programming than in most other things.
