Quit being pedantic and try to understand the concept I'm expressing, not just semantically parse my sentence looking for the first quibble.
There are only a few dozen PhDs working the BSL-4+ labs worldwide. And they have state security and state intelligence services constantly monitoring them. The BSL-1 workers (a few thousand like you mention) have access to only much lower risk bio assets/risks.
And the underlying message is that the LLM empowers 8 billion people to do some of what those scarce dozens are doing.
