>If a US-China War was to arise, worst case we would probably see a mass reversion back to 2018-22 level technology, which isn't the end of the world.

It wouldn't be the end of the world if those 2018 chips came at 2018 prices and only impacted commodity stuff like phones, datacenters and laptops, but they'll be at 10x the 2018 price and impact critical stuff like automotive, the cars and trucks that gets your food delivered to the supermarket, and if those become impossible to buy or fix anymore, then your groceries will also get more expensive, triggering an end-of-the-world riot from taxpayers who can't afford food anymore.

People need to view this issue as not just being stuck with 2018 laptops and phones which isn't that bad, but has much wider societal implications.
