The chips won't be relevant but the other items you mention could be? It's an interesting subject though, in addition there will be impacts on businesses that manufacture spark plugs, glow plugs, oil filters etc infact anything unique to ICE. Maybe as one part of the economy contracts, another will expand, rather like squeezing a balloon.

No real surprise that ICE specific kit will slowly die - probably replaced by that specific to EV as already noted. That clutches, camshafts, spark plugs, exhausts etc will no longer need replacement will be a blessing.

EVs have ECUs which no doubt adjust responsiveness, power management (performance/economy) braking regen, steering feedback etc so this will continue.

The rest of the kit - wheels, tinted windows, go-faster stripes, etc may still continue. I do wonder why people bother as manufacturers spend £££m on optimising their product only for some to later (mostly) degrade it.
