>open models are inherently decelerationist, ungovernable, and will slow development on the frontier

Ungovernable makes intuitive sense, but I don’t understand how open weight models could be decelerationist or slow the development of the frontier. Was there an argument for those positions?

Open weight models challenge the "winner takes all" hypothesis, which motivates the astronomical valuations and acts as a justification for trains of cash dumped into AI development.

In other words, if AI models become a commodity, the "AI leaders" will not be able to burn the cash like they do today, thus resulting in a "slower" (one could say instead "more sustainable") development of AI models.

It's a copy/paste of the arguments against open source software from decades ago. The argument goes: innovation requires profit motive, and profit motive requires IP rights. Of course, this was soundly disproven in software and I don't see any reason it should be different here.
