Talent is about having a right combination of biopsychosocial factors - it is just as much the individual’s skill and motivation as it is the right conducive social and physical environment that counts. Then it is a matter of targeted practice to let someone’s talent unfold.
The best example I know of unfolding talent are The Beatles - when they started playing in Hamburg in the early 60s they were plain bad musicians. But the environment was right - they attracted people, they had a few bars they could play in, they were good friends and had tons of motivation to do something great. So after 8.000 hours of playing they had become great and soon after their first hit song followed.
With designers of course it’s somewhat different as they have to work together closely with multiple stakeholders, but still individual talent needs to be recognized and fostered by a school - and the educational framework should be geared towards giving students good awareness and skills in various fields, while also letting an individual student put focus on the areas they excel in and developing an own identity and vision.
