Guys do you think that Evolvers modifications to human body are dangerous?

I do not deny that their ideas and inventions are wonderful, but the technical level and quality, in my opinion, are not sufficient or safe, such as the incident of a scout feeling pain because of a blood warmer, and even most of their artificial limbs are not advanced enough, and it seems that they did not do much of the necessary research and studies and I am also of the personal belief that those eyepieces don’t even work, and that they’re just there to make the Evolvers/Proteans look cool
