FTC chairman's comments sound reasonable on the surface, but just vague enough to be meaningless.
It sounds to me like the "guns don't kill people, people kill people" argument, but a first draft attempt to put AI issues away from the tool. Then, his definition of 'developer' is unclear.
With guns the argument is more straightforward, the tool is made to send projectiles in one direction when a user pulls the trigger.
With AI, does the end user know what the tool is capable of doing to achieve their goal when they direct it to do something?
