I am in no way near an expert on this topic, but from what I know and given nuclear's track record, nuclear energy is probably mankind's only way out of total climate breakdown.
This is the biggest reason why I didn't return to China after university even though I really wanted to. 996 is clearly violating the labor law, but big companies' spokesmen can publically admit they will enforce 996 without any major backslash.
The fact that 996 has become a norm among business lines is REALLY terrifying.
