I've always wanted to learn to sing.
I've read books about singing.
Watched videos.
But singing isn't something you learn by watching videos or reading books.
You learn it by doing.
A singing teacher can be a great help.
"Not bad. Try again with your tongue flattened slightly and the tip touching the back of your front teeth."
The challenge is that teachers can be expensive. Finding one you gel with can be difficult. And none of them are going to spend twelve hours a day patiently listening to you practice tongue placement.
For most of history, this is how people learned mastery.
They became apprentices.
The challenge is that apprenticeship requires constant feedback - which doesn't scale.
Until now, perhaps?
The real opportunity of AI in education might be access to the feedback loop.
At three in the morning.
Patiently.
At scale.
For free.
For the first time in history, that kind of relationship may be available to everyone.
Which is great, but it invites some interesting questions.
A good teacher doesn't just give instruction and feedback.
They inspire.
They challenge.
Sometimes, you just want to be just like them by being in their prescence.
Is there something about achieving mastery that resists scaling?
