> Underground AI will not be widely used.
“Underground” (that is, trained, at least in part, outside of the control of centralized vendors) AI is widely being used today in the AI art space, I don’t see why that won’t be the case for LLMs once there are modestly performant LLMs with decent end-user packaging that run tolerably on reasonably middle-tier consumer devices, which seems to be rapidly approaching.
“Underground” AI won’t be used by big, risk averse institutions if centralized offerings have the capacity and freedom they need without too much of a price gradient. OTOH, it likely will be used be “move fast and break things” orgs as they ramp up (potentially even if regulated, if they can find a way to “launder” their use) until they get big and risk averse – perhaps making it less underground in the process.
