Well look at something that might change your mind: there is this device called Muse headband that actually uses your brain signals to help you meditate. Meditation is a tool of mindfulness, and with some progress it helps exactly that: control and know your own thoughts.

So already at this (primitive) iteration of tech there is a device that connects to your brain and helps you do something, something that you would find very useful no less, if your goal is to learn to operate your brain in the best way possible. Now this is even possible with this (primitive) iteration of this tech. The effectiveness is reported by a lot of people, and it is also calibrated on tibetan monks who meditate for a living. There is also a similar institutional device with more thorough processes called "40 years of zen" (but you have to go to a laboratory).

Now imagine what the next iteration would make possible, and for example how good would a device like this be if it could actually read direct signals from the brain instead of having to read them through the skin?
