Agreed. The huge leap-forward in capability already boggles my mind, the fact that I can run it _on my desktop cpu_ and have an interactive, natural-language oracle of the internet in a mere ~11GB file.
Everyone seems to be chasing the network-accessible API approach because lock-in is easy and if you're at the bleeding-edge (training) you've got the compute for running it anyway.
But now with accessible, local models my bet is on bored young hackers coming up with the best use cases and killer apps, not Microsoft.
