Second, what to say that in 10 years ONLY big tech companies are going to be running LLMs? I realize training an LLM is a HUGE effort, today. But they will likely get easier to create over time. 
I hope it's clear I'm not disagreeing with you, you're instinct is correct. I'm just saying we can WANT a different result and work hard to make it happen.
