Indeed. We seem to assume semiconductors and computers are unlimited. It is just not practical to use your dog, a raven, or yourself as a Turing complete machine. You can't run Google on your Dog or yourself.

Hence, keeping "unused" electronics around might be wise, given the so called "unpredictable future" and supply chain interruptions.

Arguably, old and slow tech is still better than having nothing, as you do not have to do these boring computations by hand.
