Meta CEO Mark Zuckerberg has previously said that the company is working on a system that will allow you to type directly via your brain. According to MIT Technology Review, the tech giant was actually able to successfully create this technology, with the system capable of accurately determining what key the user was 'pressing' about 80% of the time. This probably isn’t an impressive number to skilled typists, but we must remember that this machine reads your brain signals externally — no implantation or invasive procedure required — which is a feat in and of itself.
However, don’t think this is a comfortable hat that one could just wear anywhere, day to day. Instead, it’s a massive and expensive machine that needs to be used in isolation to work effectively. Forest Neurotech founder Sumner Norman likens it to “an MRI machine tipped on its side and suspended above the user’s head,” with one device estimated to cost $2,000,000.
