If you take all operational nuclear reactors safety records into account from all countries in the world, including all meltdowns and near meltdown disasters, it's still by far safer and has resulted in less deaths and long term illness than any fossil fuel, on every single metric.

True that newer style reactors are far safer, but that's the point. If we had started to transition in the 70's into nuclear power, we would have made a massive dent in climate change and set the stage to transition into full clean renewable energy sources and along the way improved regulations and engineering standards for existing nuclear plants.

Isn't there Thorium reactors or something that should be some of the safest. And the waste can't be turned to nuclear weapons. So it probably won't be used :(

I don't really go on Reddit, but Idk where you live, but in my experience talking to folks, most people are pretty put off by this view

Nuclear power plants generate waste very slowly—slowly enough that we won't be using fission any more by the time it becomes a serious problem. Fusion ignition was achieved recently, so it's only a matter of time.

However, nuclear power plants are also extremely expensive to build, which seriously limits their practical usefulness.
