I think the applicability of techniques go both ways. Similar to what Sarah's dad said, I see research in ML now which rehashes expertise from many decades ago. Conversely, I see the demoscene implementing ideas on old hardware that, as you said, it would have been amazing if the technique was known at the time, but it simply wasn't conceivable then. It's only with advances in tech and lowering of technical barriers that new ideas are explored.
In any case, it's compelling to see people's expertise applied wherever.
