I don't think I learned a single thing from that entire article.

I might be in a bad mood or just am already familiar with the subject (from reading hacker news frontpage??) but the gist of the article is that we stopped doing things with one agent and now we do things with multiple agents and this is somehow (unspecified) better.

For problems that are limited by tokens/second, well, this is rather self obvious how it helps, for other problems... what? He made a big deal about agents "sending messages" but how is that functionally different from the internal transformer/attention operations except now operating over tcp?
