This is not necessary: my Librem 5 doesn't rely on blobs in kernel and runs FSF-endorsed GNU/Linux, PureOS.
PPC offered tremendous promise in the early 1990s at the same time Motorola's evolution of M68k was lackluster at best - so it made perfect sense that Apple would need to migrate away from M68k, and PPC was the optimal choice so as not to compete directly with hardware used by the PC market.
And when Intel/AMD were innovating tremendously in the early 2000s while IBM was lagging with bringing out aggressive updates to their PPC line, the switch to Intel seemed inevitable.
Even the idea that Apple should heavily develop their ARM mobile chips for future Apple products was discussed heavily in my circles since about 2016 (around the same time Intel started to stagnate their offerings). The earliest I remember was this blog from 2011: https://www.mattrichman.net/apple-and-arm-sitting-in-a-tree/.
The M1 felt like that all over again. I didn't really get that feeling during the 68K to PPC era but that also wasn't handled as gracefully.
The question is now, how many years until they start moving features behind the paywall like limits on how many people in a message chat? Or view limits (aka twitter/x) I suspect 3-5 years.
Barring some world ending apocalypse I find it hard to imagine that, even if let's say 1000 times less written material survived the next 2000 years compared to the 2000 that preceded us our descendants would still have several magnitudes more information about our times than we do about 0 BC (especially if we're talking about Britain or pretty much any people in Europe who did not speak Latin or Greek).
The things that make it through these periods are the stuff that is seen as useful to the folks in between. This is why we get a lot of religion, the odd bits of sciences stuff, a lot on growing food and snips of history if lucky. Heck for the might of the Roman empire, we only have 25 seconds of sheet music remaining. It is also funny how little we know about some of the Emperors. Things like, they had children, we do not know their names or if they survived childhood. The gaps are huge.
The things that survive are the things other think are worth surviving. Hygiene practices yes! Tiktok... no.
