Lots of products only work once you have a couple of eager collaborators.
These are extremely hard to bootstrap, even if they're very powerful.
But LLMs are infinitely patient, always game to do whatever you put them up to.
LLMs can now be your eager first collaborator, making it much easier to get these kinds of multi-player systems off the ground, useful even with one human in it.
This allows network effects of collaboration to boot up faster.
Google Wave wasn't wrong, it was just very, very early–and didn't have LLM collaborators.
"Google Wave but for you and an AI to collaborate" could be a powerful product category.
