If you have a significant other who is also making tech money and is willing to keep doing it, this will be easier.
Get a Patreon or similar up as soon as possible. "Patreon paid for my drink at the artist meetup!" is a milestone worth celebrating as much as "Patreon paid all my bills this month with money to spare!".
As a developer but not artist, I have no such edge.
Of course game design is the other big beast.
That said, I'm one of those artists who was consumed by tech because I have a lifelong interest in computers. Working on an out myself. Life's short, and it's really happening. My patience for scrums and HR-organized slack #donut meetings is waning. That's not the life I enjoy living, or want to promote to my possible children.
If you're an artist, I recommend doing research into grants. I'm from Canada where our current federal government improved the grant system recently—but there are also third party organizations that offer them as well. They are attainable.
It is work to get them, and you have responsibilities—like tracking valid expenses, some deliverables, and so on. But if it enables you to spend more time on art and less time on building half-baked software projects for cynical gold-rush pursuants (allow me my facetious remarks) then it's worth it. They're not going to pay your entire way, but they will help subsidize expenses for materials, studio time, promotion and marketing, exhibits and concerts, and so on.
Kidding (sort of) aside, I've known a surprisingly large number of professional artists and all of them had a primary source of income that had a much smaller salary than a software engineer. None of them could subsist entirely from art.
It's an unfortunate reality that artists, unless they're focused on something "practical" like wedding photography, really can barely scrape by as a career, and that nearly always includes having a part time job and a partner with full time income to make it even possible. Even people like professional symphony musicians often need an extra job to get by.
If you're in tech and interested in the arts I would start making art in the evenings. If you have a laid back tech job you should have plenty of time to devote to what you're interested in and will have an income, even at a low paying tech job, that will make you the perpetual envy of the artist friends you make along the way.
tl;dr there is no such thing as a "career" in art. If you're passionate about art, just start making it.
The laid back tech job is tricky to wrangle in my experience. Like people inevitably say in all the blue-collar threads on HN, tech jobs have a way of sticking in your brain well after the official workday is done. That really dampens my creative energies. It could be that I'm not picking sufficiently laid-back jobs though! I've always wondered, what sort of tech areas would be the most laid back? Enterprise stuff? Government work?
I make art all the time, during work hours even! I work remote though.
Edit: i see now, fxhash isn’t quite that, but mentioning generative art and blockchain got my hackles up immediately.
I have a hard time seeing generative art as a market for single pieces, but you can get work as a vj
Art can be incredibly rewarding just doing it for yourself, and from my perspective I'd find it hard to have an artist career without first knowing my own artistic expression.
I'd also be interested in figuring out how I can utilize my tech experience towards a more artistic kind of career. I paint outside of my day job and I wish I could bring the things I love about it, open-ended creativity, curiosity, etc, to my career.
Step 1: make art
Step 2: don't starve
Big difference between tech careers and art careers is you probably won't find anyone to hire you to be an artist, it's more entrepreneurial than that.You also can't decide today, with no prior training, that you'd like to be in Broadway musicals, do a workshop or two and then get your first gig. The career change arrow doesn't point both ways even close to equally.
Trying to be creative on demand is very difficult in the best of scenarios, and trying to be creative on demand when your (shitty) income relies on it is massively more so.
