Showerthought: I just read that a BCI can now type at 90 words per minute

I was looking at a study from Stanford University from last year. They had a person with paralysis use a brain implant to control a cursor and type on a screen. The speed they hit, 90 words per minute, is almost as fast as I can type with my thumbs on my phone. It really hit me how close this tech is to being a real tool for people, not just a lab experiment. The paper said they used an algorithm to read the brain signals for handwriting. Has anyone else seen practical speed numbers that surprised them?

That Stanford study only had one person in it, right? 90 words a minute sounds great in a headline but how does it work after a year, or for a hundred different people? These lab demos always hit a wall when they try to leave the building. What good is 90 wpm if you need brain surgery and a supercomputer to make it work?

Yeah baker.ben has a point about it working outside the lab. That 90 wpm is crazy fast but it's still one person in a perfect setup. The real test is if it works for my grandma without a team of engineers in the room.
