I think we shouldn't have calculators anymore either. The world was better when we had to calculate everything by hand and a human by hand verified every single addition and subtraction.
I'm not sure the world is better if everyone was forced to do TLS handshake math by hand.
The last couple decades of economic development (of the first world at least) was in a large part due to the efficiency gains by not having people do math by hand. The world will definitely not be better if you just blew up all the computing tech since calculators were invented.
Yes, I am being sarcastic.
