The licenses governing use of these AIs and the fact that no one besides major corps have the hardware and manpower to train/tweak these massive AIs means they have and maintain an upper hand in making and selling these AI platforms.

Interesting article. Thanks OP for posting.

It’s notable that even most major government departments or agencies in the OECD would find it difficult to justify the resources, 10s or 100s of millions of dollars, required to train an AI, even if they have sufficient staff with the expertise. That means these not-so-open source AIs aren’t accessible.
