The fact that we can apparently detect repeatable patterns of brain activity, and do it across a few modalities (handwriting, cursor movements) shows that a lot of the core problems are solved. We’ve achieved Proof of Concept.

With greater sensor fidelity, greater quantity of data, improved ML approaches combined with alternate detection targets (particularly subvocalisation) means that getting to faster than parity WPM seems like a realistic result. Incremental improvements to tech is something we humans are quite good at.
