You will not believe it - while you are only making a decision for yourself whether to develop it or not, Elon Musk presented a prototype of this technology called NeuroLink a month ago.
Great, isn't it?
The typical time between obtaining a scientific result and its implementation in the form of a real technology is 30-50 years. If you assume that some imaginary technology needs 10 times more to develop, then there is no suitable scientific base for it yet. So it is worth switching to it.
And science is an interesting occupation in itself, without any connection with potential applications.
