Brain machine interface chips

I thought about this literally in the shower yesterday as I was trying to prop up my waterproof bluetooth speaker somewhere I can hear it clearly. I like listening to music or podcasts while I'm in the shower.

For some reason, the speaker didn't want to stay in its usual place and kept sliding out.

Then it occurred to me. If I had a chip connecting my brain to my devices, I wouldn't have to deal with any of this. I could, well, you get my meaning.

I won't buy one from Elon Musk but the technology is tempting.
