I notice modern intel chips are still named after Skylake. It's as if that's when they decided to stop innovating.
They used to use completely new names for new designs and then variants of that name for variants of that design. As in Sandy Bridge and then Ivy Bridge. Haswell, then Broadwell. Skylake, then Kaby Lake. Then Coffee Lake. Then Cannon Lake. 10 years later now they're still doing Lakes. It might not have much relation to the technical design but it gives the impression they gave up on new things.
AMD names their server CPUs after Italian cities.
Sometimes naming is just naming. No further depth or symbolism.
Skylake is when things started to go south, outwardly facing. But it was even long before that. The rot happened in the foundry side and it grew for a very long time, silently, because of how little competition existed.
Everything thereafter was pain.
