Lol I don’t think it’s that easy to mind control with just a chip. I’m talking medicine, if any kind of mind control was possible then it would be how every other medicine works. Nothing works without the ‘communication cure & lifestyle adjustment’ Take diabetes for eg. You can take all the diabetes medicine but if you’re consuming sweet or carbs then it may not work, it’s the same with every medicine and every surgery. So in the theory, it wouldn’t be possible to control anyone’s mind with just a chip. A part of the brain that controls motor function to help people with paralysis is doable but other than that, every part of the brain doesn’t have the same function and therefore can’t be controlled with just a chip.
