Mostly sys-admin stuff, a lot of terminals, ssh, config editing, minor programing. but I keep a few desktop utilities (gimp, inkscape, blender) for when I want to make pictures, notably absent is a file manager, the shell takes care of all my file manipulation needs. but if I had to recommend one it would be xfe.
Speed-wise I think is is more sluggish than a linux system. I like and keep it because openbsd is so comfortable. openbsd was the first operating system where I felt I understood it and it's motivations. every once in a while I try to replicate my preferred system on linux(void linux comes close to what I like about openbsd) but usually find myself back on openbsd(usually with a sigh of relief) in a couple of weeks.
For me it was that it worked mostly just like Kakoune (or at least, the parts i used of Kakoune) with nicely integrated LSP. It also had TreeSitter based movement options and themes, which is really interesting too. A potential future where vim-like navigation is done on TreeSitter objects is attractive.
The potential DSP integration is nice too. And to top it all off, it's made in a language i enjoy and within the first 24h of using it i had a PR made for a small feature i wanted. Being able to contribute in a language i enjoy was nice.
I don't use either one, but just from reading the comments here: using treesitter for syntax highlighting and having LSP configured out of the box (for kakoune I think you need to install an extension called kak-lsp).
The blobs on POWER10 as I remember were firmware for the memory sticks themselves since it used OMI to talk to the DIMMs, and IBM had to get third party OMI<->DDRX controllers. I see why they could have reason to believe that situation could change.
So really it's just one guy on phoronix who made that claim. Probably just wishful thinking. But if it is true, everybody with first-hand knowledge of it would be under NDA. So we'll probably never know.
Yeah, I was wondering the same, I know for sure it's not the industry I'm in, which is now "mature" and boring. It's probably something we're not even familiar with because it's so niche. Or maybe it is something that we know, but to our eyes it doesn't seem that powerful. In the same way that people used to think of computers as just tools for doing multiplications and other arithmetic operations and they could have never imagined everything else that computers do.
