How many of Microsoft's 221k employees exist solely to support the weight of a company with 221k people? A smaller IT department doesn't need a large HR department. And a small HR department doesn't file many tickets with IT. LLM driven multinationals will need orders of magnitude fewer employees, and that puts our current multinationals in a very awkward position.
Personally, I will be storing a local copy of LLaMA 65B for the foreseeable future. Instruct fine-tuning will keep getting cheaper; given the stakes, the large models might not always be easy to find.
This entire legal argument is almost beside-the-point because development on open source models can continue on onion sites too.
It will only affect commercial operations, and they won't be able to release a fine tuned model on a banned LLM even if they do have a pre-ban copy saved.
