But we didn't even become more careful with existing reactors. The companies running them kept being textbook capitalists and cut costs wherever possible. Outsource maintenance to questionable Eastern European workers. Inspections reveal unexplainable micro fractures near the reactor core? Just declare it safe and carry on. Workers on-site monitoring the operations are retrained electricians, because well, both things have something to do with electricity right?
I'm not afraid the technology is inherently unsafe. I'm worried because it's run by companies maximizing profit, and regulated (indirectly) by politicians caring about getting re-elected, and maybe about their hometown/electoral district.
