Gruber was a good voice in the industry but this article misses the mark in a lot of ways.

A company the size of Anthropic would not voluntarily jeopardize their massive valuation if they didn’t feel the resulting output would maintain a similar level of quality as before. Is there a similar worry that their system prompt, which is injected at the start of every conversation also influences token generation in an artificial way?

If regulation will ruin Claude as a product, market forces will fill the void. There are also a ton of open weight models to choose from. It’s going to be okay.

Gruber is not much of a details man - he helped invent Markdown (to be lauded) but ghosted its standardisation. I would be fascinated to hear Prod John MacFarlane of UC Berkeley's opinion on it all given he was heavily involved in the push to get Markdown standardised.
