The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)

All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:

Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.

I remember learning about this back when I took a smog certification class back in community College. Learned the only computer approved to run the modern smog diagnostic stuff is from 1986 and it's made by like one company to this day.
Add onto that all the dinosaur lathes and welding machines I've seen over my career and I wouldn't be surprised seeing a commodore running the dmv database for the entire state at this point.
"Ancient" lathes, milling machines work fine. You don't need the newest control software when the old one does the job. And good luck convincing someone to buy a $100k machine just because it is new.
Usually, you're right. But having the actual machine is only half the problem.
Last place I was at we had this big beautiful ride along mill that was just magnificent. Between the attachments and tooling we had, it was capable of producing any part of itself down to the last nuts and bolts. With the right know how and materials, it was capable of self replication.
We torched it for scrap. Not me, as a dumb dumb welder, but the business. There was nobody we could find with any combination of a) space to put it, b) ability to pay for it, and c) know how to run it. Best we ever managed was two of the three, and since there was no money in it for the business, they elected to cut it down for scrap value. Got one of the best t-tables I've ever had to weld on out of the deal, but it was still a travesty.
So yes, while the machines work fine, it's hard to find people with the skills to run them effectively, the space to actually house the machine, and the spare cash required buy and maintain it.
Well, yeah you need people to run em, maintain them and you need the space. Thing is - most people wouldn't be looking for an older machine specifically when needing to buy something. Those machines stay in machine shops and crank out parts since forever.
Like, a neighbor of mine has three older lathes, one cnc, one larger, one smaller. He had to redo the wiring from scratch on one of them because it was so old the isolation from the wires fell off and it was just copper left hanging in the control box. No company would buy that stuff.
