Is it true that fusion power is "only" four times more efficient than fission power?

I don't understand how red giants work.
You can't just make a star 100 times bigger and still have a star, it would just be a huge gas cloud by then with no fusion.

I like to imagine an ai introduced to the public as a hardcore gaymer getting into a messed game of base building management it has to clean up.
It will take time but when working with humans it will be plenty occupied to try and optimize everything.

The radiation is not ionizing and should thereby not be dangerous.
But I can shake the feeling that being constantly swept in man made radiation must have some effect on us.

We have evolved to tolerate solar radiation during the day and background radiation at all time but how does our bodies react long term to all this extra radio and microwave radiation?
