Most such startups are scaling up the number of electrodes interfacing with the neurons to overcome this bottleneck, but I wonder if an unconventional approach could overcome the limit more gracefully. I may be a dreamer, but a high fidelity synthetic neural fiber is the holy grail here. I do remember reading people partially healed of paralysis due to spinal injury, because of electrical conduits that bridged the injured neural gap.

The ability to produce sound without a use of a dictionary sounds awesome. It is an interesting result, a proof of concept as the author of the study says, but the title is editorialized at best and effectively clickbait at worst, because most readers will assume that "near instantaneous speech" means "clear intelligible speech and ability to communicate".
