Dangers of allowing advanced technology in immature worlds

[unity100]

I don't think so. It is so easy to blind people with powerful lasers. Airsoft guns can blind as well but airsoft bullets don't accidentally reflect off surfaces into people's eyes.

having said that, I still think technology is good for humanity. Including lasers

this gun can pierce simple substances however.

all that limits this kind of weapon, currently, is power.

if, free energy devices are available, then it will be possible to make much more powerful lasers with these.

considering how a single individual, in his hobby time, constructed this contraption, with free energy devices the magnitude of destructive power small groups and individuals will be able to play with will be magnitudes greater.
