I think that's equivalent to asking everyone to go to chef's school and describing the upside as 'People will realize that peeling potatoes can be done in a quarter the time they're doing it now!'

It's just... why? These people aren't going to be doing any programming daily. Why don't you take all that money, and all that time and let each non-programmer go to a deep dive conference of their choice for whatever their discipline is. Seems like a much better use of resources.
