I think you’ve been staring at a crypto miner a little too long fren. Having your computer network in nanomachines spread out In humans all over the place to do computational work is highly inefficient. You need wireless transmitter and receiver, a power supply that somehow uses the human body to power itself, a cpu and ram to load and manipulate whatever you’re sending it to do, all the while keeping it in the body and not removed by natural functions and deposited in the colon before taking a toilet plunge. Occam’s razor this situation. You have a technology (mRNA) that they’ve been working on for decades and haven’t been able to make a dollar back from all those billions invested. They get it to the point where it SEEMS like it’s not going to kill the victim whops I mean subject. They push it out in a hurry with no one wanting to rock the boat. Middle managers don’t care, they need their job. The technicians have spent their lives getting educated and working in this field and can’t fathom doing a different kind of job much less getting hired anywhere else if they blow the whistle, the other major players are doing this too so there’s no where to go. Not every corporate bad guy is a Bond villain most of them are just Dilbert’s pointed headed boss.
