Lex Fridman interviews Bryan Johnson, founder of Kernel and previously Braintree, about brain-computer interfaces and Kernel's non-invasive brain monitoring hardware. It covers what the devices can do today and the company's plans.
Cited as an accessible overview of Kernel's technology whenever its brain-sensing helmets come up.

>No one cares about someone’s improvised broad generalizations and “one day it’ll be great” patronizing speeches. I was just matching the patronizing, brusque tone in your original post. >The question was what’s it good for as it is today, based on people with knowledge about it. I apologize, then, because I don't think that was clear from your post, which contained only the text "So what is this tech good for in the first place." If your question were "So what are the device's current capabilities?" or something similar, then I would've responded differently. >In particular the only thing you demonstrated here is that you have absolutely no knowledge about it. I do, actually. Your question (ending in a period) came across as extremely condescending and dismissive, and as if you were questioning the value of BCIs in general. So my goal with that post was to try to make an argument for the potential of what BCI tech is good for in the first place, as I interpreted your post. If you want an overview of what their company's devices can do today and what's planned, this recent podcast episode with the CEO is a good start: this video
Following blog post talks more in detail about his meals/daily diet: [LINK] See also where he talks about this a little bit with Lex Fridman. I watched the video first then poked around on Google a little and found his webpage. [LINK] Full podcast which is more about Johnson’s brain monitoring device: this video Note I don’t have any affiliation with Johnson or Kernel, just enjoy Fridman’s podcasts.
Johnson was on the Lex Fridman podcast recent and discussed the helmet there: this video The most interesting thing is that one of their helmets, Flow, is using IR backscatter sensing rather than the electric or magnetic sensing that most other BCI devices (including their other helmet, Flux) use. The system is still pricey at $50-100k or $3.6k/mo, but they're also planning on selling a simplified version at $5k: [LINK]
