The details matter. Will it hurt? Is it subsidized and will be more expensive later or the other way around? How's the latency? What killer apps? Is it under health privacy laws or typical internet privacy laws? What likely side effects are there besides laziness?
It does sound useful. Like go to the mall, look at a keyboard, immediately search up the reviews, then the price elsewhere, sort by nearby. Or in an interview or during a meeting, just search the answer on the spot.
Re pain: the brain "lacks pain receptors" according to standard thought (tho same can't be said for the meninges, so I guess all bets are off). Tho what about emotional pain? Increasing the signal/inputs might increase possible negativities (tho chips would probably monitor and adapt your "recommended content and styles" to increase pleasantness - taking "brain hacking" to whole new level I guess). And interfacing with it might might consume more "mana" making your brain hurt due to depleted resources. Idk.
