Agreed with your rant, but this time they won't get it both ways. The cats not getting back in the bag, the papers are out there, the knowledge is out there. Let's say the US bans DeepSeek from operating in the country. Firstly, just look at immensely succesful crypto casinos like Stake, CSGO gambling websites etc for examples of how trivial this is to get around, but let's say enforcement here is stronger. How are you going to stop people running their models locally? How are you even going to tell whether a model originates from e.g. DeepSeek or Llama or whatnot? Provenance, lineage? Are you going to ban the running of LLMs by anyone not called OpenAI altogether?
They won't get it both ways not for lack of trying or will but lack of feasibility in this specific case. It's too easily accessible. The single way to do it would be to set up a level of surveillance and control that ironically only China has in place. And even if the current government openly becomes a dictatorship, it would take an incredible amount of time and dedication to get something similar in place.
