Theres just so much you can do with that outside of the normal done to death reincarnation tropes

Like, what does that society LOOK like, what do all those outside cultural and technological contexts DO to things like architecture, tradition, law

It would probably be better if most people just had vague personal memories, just to keep it from being an expectation that at some point you have to sit down and barf out all the technology you can remember.

weird 2am thoughts, i should revisit this idea during waking hours at some point

DUDE DO YOU LIKE. Have a priesthood in that world that does their best to catalogue reincarnated memories and technology? The brotherhood of the memory or something????

do they decide what vaguely remembered tech should be further explored and what should be off limits.

(could also track and distribute culture, potentially, I just instantly latched onto a technology priesthood)

I could also see tech being slow because the number of people who are reincarnated engineers are fewer. Like, I know physics, but I couldn't make a cell phone.

thats a good point, and MOST of your information is going to come from people familiar with the end product, not the technology it takes to GET there. In the end it probably DOES speed their development somewhat, but also results in enough dead ends that its not like, purely a benefit.

that does mean technology probably moves in surges, as suddenly a missing foundational piece is identified and a lot of things that were tried and failed before suddenly make sense

but thats at like, the macro scale, year over year its probably pretty slow
