It's too early to tell, but given current technology I'd say BCI is a hard egg to crack. Being someone that have been working on it for the last two years all I can say is that it's too noisy and unreliable. There have been some excitement with using ML/DL as improved decoders but it's still hampered by myriad of problems for it being a product, or even better than existing interface devices. Working with those devices suddenly gives you a massive dose of scepticism to neuroscience papers that use hose devices for experimental verification of their theories. Advancement in (hardware side) ECoG is the only way I can see it get better but that's still far fetched
