That’s all true, but there have been a few things similarly widespread and harmful, which weren’t solved until their turn came. Like lead in everything (not that nobody knew lead is poisonous or that things containing lead end up in the air and in the water and so on), or like child labor in factories, or like slavery (slavery was considered barbaric and gradually outlawed in Europe in the Middle Ages, then it made a comeback during the triangle trade, and for all its time of relevance people argued about its social effect, and that of racial segregation, still it lasted long enough).
This is a problem. It will eventually be seen as a threat. But it’s not that much different from radio.

Which you often don’t need. Mechanical computers for aircraft operation, or hydraulic computers for modeling something nuclear, things like that.
But there’s nothing “century-old” about all this. They might have non-deterministic steps for some calculation where determinism is not needed (like if you need to ray-trace a sphere, you’ll do fine with a bit different dithering each time) and without it better performance is achievable.
The idea seems to make sense, just - it will never be revolutionary.
