Software development is only a well paid profession fairly recently, and only a very well paid profession if you are lucky.
Also I would consider a bare six figure salary well paid.
That's because you're not very old yet.
IF remote jobs and wfh culture will rise, I would bet those salaries are gonna plummet down in the medium term
Outside of a few hotspots like Silicon Valley, programming salaries tend to ramp up quickly in the first few years then hit a plateau. Other professionals like lawyers, accountants, doctors start more slowly but their plateaus are much, much higher. This is why 25-year-old programmers think that they're rich. They haven't hit that plateau just yet, but most will, and sooner than they think. And not long after that they will have their first encounter with ageism. A lawyer or a doctor will never experience that, because his profession values experience. That is the hardest part of staying in this industry for decades, you get to see all your hard-won knowledge become worthless, for no reason other than fashions change.
The vast, vast majority of programmers aren't in tech firms, they are writing internal software for companies in other industries for whom software is a cost, not a profit centre. Those programmers are paid the same as any other mid-level office workers. These programmers are barely represented on sites like HN however so they are almost invisible.
With every abstraction away from the core computing libraries, you take a bigger risk and enter into a bigger gamble with your time.
I certainly know I am keeping miles away from node and webassembly (although the latter is interesting), simply because I was under a guy who has focussed his efforts not on acquiring fancy knowledge, but rather using simple techniques to achieve complex results.
Soon the very simple things I learned to appreciate, ended up being things I now use every single day to do stuff way more complicated than a person of my intellect should be able to accomplish.
Anyways, this got kind of sidetracked on the way, but I have to work with colleagues who have cemented years of knowledge in archaic tech, that while current at the time, ended up fading away over the years. They still have knowledge and skills, but they let their experience shackle their thinking, and oftentimes come up with extremely complicated solutions for very simple problems.
I think this is also the point in their lives where they got comfortable enough to think they don't need additional training, where I was very much taught that there is no limit to knowledge that can be acquired.
