New concepts like this that feel like straight out of a sci fi book always makes feel uneasy, but you have to udnerstand that research of spaces like these are the key for us to continue developing, computers and cameras and radios also felt uneasy for humans hudreds of years ago. Also "playing god with things we dont fully understand" if we dont start researching it we woll.never understand it, we should research it and that will lead to us fully understanding it and then it wont feel like playing god.
