To stick with the analogy, this is like putting a small CPU inside the bottle, so the main CPU<->RAM bottleneck isn’t used as often. That said, any CPU, within RAM silicon or not, is still going to have to shift data around, so there will still be choke points, they’ll just be quicker. Theoretically.
Thinking about it, this is kind of the counterpart to CPUs having an on-chip cache of memory.
Edit: counterpoint to counterpart

Save your effort. What’s already there is there forever. They can just roll back your comments, or even, if they’re in the mood for it, make it appear under an entirely different username.
The only way to win is not give them any more. And that fight is already under way. They’ve already started recommending old comments after new ones because the quality isn’t as high any more.
Think about it: The only people who contribute to Reddit now are the clueless and the sort of people who have willingly stayed.
I like to imagine Spez stomping around saying “Hmph! Hmph! It’s not fair! Why did they all leave?! They’re stealing my revenue by not giving me anything for free”. I mean, he’s probably not doing that, but I do like to imagine it.
