I know someone who sells those systems, and everything associated with them. He's been doing it for about 10 years I think and crushing it by fiat standards. He works constantly though and doesn't get to spend much time with his family which is sad

I sold high end software for 25+ years. It’s a very lucrative career in fiat terms but it’s a tough world. Not many survive over long time periods. Unless you’ve been in it, it’s hard to describe how different a world it is from regular jobs.
