If you can afford a brain computer sure, but for everyone else, every 20th sentence will be an advertisement for Doritos.
Surely brain computers will be a pretty big investment for people; would embedding advertisements be worth it for companies? I'd imagine most people are willing to pay another few thousand dollars on top of the very high cost to avoid any sort of obnoxious features, for both personal and potentially socially-influenced reasons.
It's hard for me to see how anything could be worth more to companies than straight profit.
you think fb will make people pay for it to receive like notifications in your brain?
But what I was saying is that even if you could pay for a brain computer, many less fortunate wouldn't be able to, which opens the road for advertising subsidized (surveillance) brain computers.
