Who said anything about "serious"?

(FWIW: I suspect there are more than a few old industrial control systems and such out there that are still running DOS, just because of an "if it ain't broke, don't fix it" attitude)

My brother is in manufacturing. DOS is everywhere. Older things too (PDP-11? DG Nova? Seen both, semi-recently). Not just because "ain't broke, don't fix", but because when you have a cloth dying machine or brick forming machine you spent >US$5M for, that is often a bespoke install for your plant, you don't replace it because some guy who prolly slings Javascript all day sez "DOS is oooold, boomer".

		These DOS machines for industrial control could probably be replaced by an Arduino or a far more reliable MCU, whereas running an actual legacy PC as a business-critical component in manufacturing has to be a bit of a nightmare by now. AI could probably do a good enough job of working out how the legacy DOS executables were intended to work.

		Given the implications, I guess nobody is going to touch those setups to put an SDL-based program on them, though...
