State-of-the-art technology is very impressive, but I think the harms outweigh the benefits. Work must be done to find a way not to cause harm to animals, to the environment and from people.
And once this has been studied, this technology should have been implemented, at the moment I think it is not necessary that we have it or use it.
Yup currently its best for companies to wait for scientists as well as developers to come up with ways to negate the side -effects of 5G and then launch it.
