So vague it’s useless.

We cannot in a declarative sense define what is economically valuable work even now let alone into the future.

People take what they can get for pay. Very few individuals can demand a wage. The value of employment is obviously designed around that, not some arbitrary definition of “valuable”.

Of course an AI will accept $0/hr, it doesn’t mean it does the job.

Anyone who could accurately define the value of work would be wildly successful without having to try.

That is not a useful definition for me unfortunately.
