It's inevitable but I still don't like it and I don't think I ever will, honestly.

Also I don't believe it will be fully controlled by the end user. We've been heading in the direction of less and less control over our own electronics for a long time now and I don't see why that trend would stop, given that it's clearly more profitable and most people don't mind giving up the control. Especially given that you can't just get rid of your own brain implant in the same way that you can install a new OS on a computer or toss it in the trash if you really hate it.
