> Also love: scientists get to pay Anthropic to work within their special science harness to do science. That's exactly what I dreamed of doing when I pursued physics in undergrad, one or two companies holding the keys to "progress" for a monthly subscription price.

The moat is very limited. Harnesses aren't crazy hard to engineer. Open models are quite capable.

Agree with you, but not sure what form the arms race will take as the months go by (between harness engineering, RLing models within harnesses, etc)
