For those who didn't figure out consequences.
Rapid advance in any infustry requires higher energy usage. Since nuclear isn't used, speed of advance was slowed to incremental by need to first increase energy efficiency before moving forward. And increments easily got swallowed by inflation.
Only semiconductor industry has advanced rapidly thanks to Deming rule, now not operating. It was effective till 2005. Basic idea is than halving transistor in half improved all tehnical mesures by half. So 2 smaller halved transistors use same amount of energy as one bigger. And current advances are based on fact that relatively cheap technical improvements to transistors can keep rapidly lowering transistor energy usage.
So real price of not using nuclear is wholesome stagnation. Otherwise, all industries would advance fast as semiconductors. Remember, flying cars are practically banned.
