You realize this is what people said about solar energy and nuclear energy at one point, right
And before someone chimes in and says Nuclear doesn't make sense - it made sense at plenty of times and in different places.
It doesn't make sense in Western countries that are hell bent on making it as expensive as possible, strictly to ensure it doesn't get built, so we stick on fossil fuels as long as possible.
This is a meaningless argument people trot out all the time for things they just don't understand. Sometimes it applies but often it doesn't.
For example, people will dismiss arguments saying FTL is likely impossible because people once said that about going to the Moon. To be fair, there was some logic to the anti-Moon argument based on physics. The big change came with multi-stage rockets that solved the weight and thrust problems. And even then it's close [1].
There are good, physical reasons why FTL is highly likely impossible. You know, based on phnysics.
Likewise, the challenges to commercial fusion are also based on physics. Fusion reactions produce neutrons. Neutrons can't be magnetically contained. Neutrons destroy the container and, more importantly, lose energy from the system.
