Does it have a promising future?
Haiku OS
no.
No, it's literary based on a commercial failure from two decades ago.
It's probably going to hang around for a good while as a hobby project, but it's hard to imagine any significant number of people using it seriously.
Which one has more opportunity to make it? HaikuOS or ReactOS.
make it where? super-niche hipster os?
ReactOS. It at least has something at least vaguely resembling a use-case.
Proton on ReactOS fucking when???!!!!!
Yeah, but only if the devs realize that two paint programs and a video player aren't worth keeping legacy support for, at least not on the 64-bit version. It has multiuser support and other modern features that are disabled by default and not available through the desktop GUI. That's what's holding it back.
Shut up, /v/toddler. Fuck off to your containment board.
