There might be some truth in what you say for very large image and language models that use supervised learning.

It is really hard to see how this 'it's just a lot of good data' view applies to deep reinforcement learning where the model learns multi step policies from raw input data (e.g a camera on a robot) with only a rough high level reward function to guide it.

If therefore (as seems to be the case) you can abstract the information humans need to provide to the model/learning system to ever high levels of reward function (and thereby vastly reduce the information provided by humans) then it seems very hard to argue that the model (and the training process) isn't doing to some degree what you describe as:

'incredible amounts of experimental work to carve-the-world along its joints, ie., to have the right concepts; and incredible amounts of work to measure along its joints, ie., to have the right units. And then to eliminate all the coincidences and irrelevances.'

For example, imagine a robot learning from scratch to pick objects up based on raw pixel data with only a scalar reward function - where in this process is the human preparing the data so the model only has to average?
