I think a brain interface to computers and phones would be useful but privacy would really worry me. Hack someone's brain, and you get way too personal info. Sometimes when I'm reading on my tablet, I think it'd be cool if it would just scroll when I get towards the bottom. Eye tracking might work, but I feel like you'd falsely trigger it sometimes. Also, I feel like I think way faster than I can type. I can visualize the piece of code in my head before I even type it out. Imagine no more spelling mistakes :) Brain surgery already seems very scary, as you have to stay awake during it. Then when they come out with new hardware generations, go under the knife again? Brain surgeries also are expensive. But I could see how something like this would make me 100x more productive than I am now. So if I created something really cool using my new special abilities it would probably pay for itself. So I see a lot of upsides and downsides. I don't know if this would be something I'd want to be an early adaptor of, though. Imagine if the company supporting it went out of business, now you have this unmaintained piece of hardware in your head. If something like this was perfected, I feel like this would be an asset to have just for the productivity advantages.
