Prototyping is what you do before you mass produce something.

As for replacement, you need three different variations - small, medium and large. Injection mould the fucking things by the shedload and they'll hardly cost tuppence.

Some people might be motivated to make provision for their descendants. If I leave them stocks or property they can get dividends and rent forever. It's an asset that gives a future income stream.

What's that up there? Looks like a stapler ... only it's red!

what you incorrectly label hardware-level override

I didn't incorrectly label anything.

By hardware level override I mean physical valves or switches that can be directly operated by humans on the premises. One would hope said humans are trained to do this in the right sequence etc.

Sure. But software shouldn't be able to make hardware damage itself.

Also, designing something like a steelworks without some kind of hardware-level override is so stupid it borders on criminal.
