My take is that "sovereign computing" will go from something 0.001% of the population cares about to over 1% in the coming three decades, i.e. three orders of magnitude. It will depend on how long we continue in the current survtech course. There is also the question of if we will see mandatory backdoors in hardware. For example, Country X could legislate that all CPUs sold in their territory need to have a latent command-and-control area for law enforcement to use. If that happens, I'll start converting my savings into a physical stash of old reliable CPUs.

In any case, it seems that CPUs have a very long shelf life; it's still possible to buy 8086 processors[^1].

Default esp32 still comes with built-in binary blobs for the radio though iirc
