There are so many situations where you can't just swap hardware. Robots on an assembly line? Yeah you've gotta use hardware that's gone through safety testing. They're not going to just swap hardware to make things easier. You want to ship an update, you do it in software and under strict testing regiment. Some of that hardware is 20 or 30 years old. Medical. Aeronautics. Aerospace. All of them and more are using older hardware that's often memory limited but can often just sit and process their next step, and they often don't have built in complex hardware features because those add potential failure points.

the hang up for me is more the not caring about time to compute

aeroish is my experience, and for me those have all cared about time to compute

generally that’s one of the biggest constraints to the point of being super strict

like major money being spent on modeled approximations and processing speed costs eclipsing pretty much everything on the design side

tables for weather, angles, altitude, position this would be tiny compared to some we’re using

30 year old equipment is even more taxed given the likely feature creep in my experience

I'm guessing you were doing in flight aero stuff? I've been more in the medical and manufacturing space but the aero I did we were doing post-flight processing for reports. We had almost no memory to operate on, probably because of all the tables you're referencing that others were using.
