Neuralink company is often missing in market reports concerning bioelectronic medicine (BEM). I would consider it a BEM company nonetheless, because brain-computer interface it is building is a great platform for medical intervention. Musk indeed mentions in the interview linked below several diseases that its technology could help in dealing with (although I have no idea why he mentions autism next to spinal cord injury). I’m keeping fingers crossed. Also, if you think that the long term vision (merging with AI) is a science fiction, remember that from a biological perspective it’s a way more realistic than Kurzweil’s “uploading consciousness into computer” and the most of transhumanism ideas.
