I can't recall who said it, but "The biggest problem with golden ages is that you never realize you're in one until it's over".

There were several golden ages of tech for most people who went through them: - the pre-internet run-up of personal computing (~1975-1995) - the early internet (~ 1990-1998) - the big post-dot com crash tech boom (~ 2003-2020, but more of a golden age for employees)

However, almost all golden ages (including non-tech ones) end for the same reason (the ranges above I'm excluding the last phase). Early adopters (tech enthusiasts), early implementations that focus on them, then mass market appeal that "dumbs it down", then the financialization as accountants and grifters start showing up. Same thing happened to Hollywood, the music industry, etc.

We're now squarely in the last phase of the post-dotcom boom.

(I'll also note that the timeframes are arguable - I'm not going to get into quibbles over minutiae)
