ethereum moved to proof of stake sometime back. BTC and I think a few other (very) minor cryptos still use proof of work which is where the significant power usage goes. Not something I track but I believe the vast majority of non-BTC cyptos are proof of stake or something not proof of work anyway and BTC is the only one that uses proof of work and is used at all. That might not exactly be technically correct but it is in the practical realm.
My Intel Arc 750 works quite well at 1080 and is perfectly sufficient for me. If people need hyper refresh rates and resolution and all all the bells well then have fun paying for it. But if you need functional, competent gaming, at US$200 Arc is nice.
I work with a small nonprofit that years ago was donated Photoshop. Over the years as upgrades happened, the org received new donations in one way or another to keep it current enough that it was still helpful. Even with a legit corporate donation of the software the license for it was a pain to deal with. At one point when it needed to be reinstalled it was no longer possible and I told the org to just forget about it. Last time I talked with Adobe to try to get it working, which they refused to do, I ended up telling them I would never use an Adobe product willingly again. I personally learned Gimp at that point and while I only use it from time to time it does the job and as you say, it is always there, always works, has plenty of online help and does anything that I need it to do.
Just like beingoff corporate social media, I try to use FOSS as much as is reasonable because while it may have rougher edges at times, it can actually be more reliable. I manage some servers as part of my job and over the years the licensed stuff, Windows server, Exchange, VMWare at some point will bite you back with a dead end or major costs where as Debian…
I assume that most of the few of these that actually get made, will end up being parked on rich people’s lawns as some sort of weird post-modern art meme sculpture or whatever.
