We can't avoid learning and discovering the power of nature and what makes stuff up. It is governments and the military who see the potential to kill or destory others. Most scientists want to make the world a better place, to do that we need to experiment, learn and develop our knowledge.
Once that knowledge is published it ends up out of our hands how others use it.
I am sure Einstein s idea being e=mc^2 was energy and power stations not atomic weapons.
@aeva @zleap Sometimes a technology just lends itself well to weaponization even if you personally don't make any effort in that way.
A lot of the parts involved in DIY engine & compressor mechanics trivially lend themselves to DIY weapons.
In this case the engine-makers are the normal people, the ones making weird shit would be the governments and other entities that just love using violence to assert their hegemony.
@zleap yup. "if I don't build the machinery of horrifying atrocity someone else will" is definitely the kind of thinking that prevents horrifying atrocities and a normal harmless thought for a curious mind to have
