It may be the case that the potential output of a worker engaging in the productive process goes arbitrarily high. But the that won't matter, if they're not permitted to. Given a choice between involving a human worker who will demand compensation, and a fully general robot, which will the owner class choose?

The vast majority of human intelligence is already squandered: millions of potential geniuses in impoverished places, suppressed by lack of opportunity to flourish. It's not about the quality or quantity of intelligence. It's about who controls it.

The fruits of the industrial revolution didn't end up in the hands of the worker by divine grace, or by some natural law. They were won by the hard struggles of the labour movements, by leveraging their indispensibility to the process of production.

If we want the utopia you imagine to be accessible to ordinary people, workers must cease being so eager to build their replacements, and be prepared to collectively struggle for their share. But if we are lulled to complacency by the notion that this will be a passive process, that struggle will not be necessary, then prospects are grim.
