you can get 80% of the juice with 20% of the squeeze.

if AI even in its current form brings those first 80% down to say 200 hours from 2000 hours before (taking the proverbial "10k hours to mastery" here as arbitrary benchmark) thats huge!

EDIT: even if it´s arbitrary, it actually seems quite reasonable: if you study sth for 6 h/d (the actual 6 hours, ie not including the walk to the library, the chat with your neighbor, the coffee break, yadayada, the pure 6 h net focus time) it would take ~1 year to reach what I would call "literacy" in a subject (the first 80%).

I´m old enough to remember time before AI and that seems like a reasonable estimate for most subjects I could think of.

Slashing the time by factor 10 brings it to ~1 month. That also sounds reasonable now.

(Im including either weekends or vacation time in the year, because its a long haul which requires more energy management; and assume that the monthly focus would be more intense)

So, with dedication, you could become literate in 10-12 subjects in the time it took you for 1 before.
