In having on-again, off-again RSI issues over the years from coding, I think this tech would be hugely beneficial and is more realistic to ship in the near future.
I don't know if it was the book, a placebo effect, or something else, but I got better after reading that.
Current BCI tech is nowhere near the fidelity of non-BCI control methods (e.g. eye tracking). If you're serious about it, look into them.
Also, check your desk and chair ergonomics. I find having my elbows on the desk reduces wrist strain.
i suppose we have language models for code now, but i suspect it would still be frustrating- at least in the short term.
but, we shall see...
