You can also do this online. In chess you don’t have complexity so the best bots can beat the best experts. You can learn languages with tapes and digital materials.
In an increased complex environment, this is not realistic until/if they catch up which is possible.
Given that the manifesto takes a decidedly humanist stance on technology its not surprising. Education isn't just about 'learning stuff' its about having institutions that form citizens and instill some sense of virtue and values, and that can't be done in front of a screen, or replaced by technology. Very relevant today with the amount of covid-related lack of socialization outside of the home.
Sure, we live in a society. I think we all understand that. Technology is there to facilitate the transmission of teaching. There will always be a group that creates the curriculum, but students don’t necessarily need to have an actual person at the intake point. So while I agree that you can’t rely solely on technology, that doesn’t mean you shouldn’t invest in it, which I fear is what’s being implied by your statement.
As a purely practical example, right now the average current ratio between teachers and students is still somewhere around 30:1 or 20:1, which pretty much makes it impossible for consistent individualized attention. Ideally we could get to a 1:1 ratio, but that’s unrealistic. Effective use of technology though can be used to dramatically improve the leverage and reach of a teacher such that a lower ratio could be simulated in some sense. Not perfect, but it sure would help a lot.
