It’s an interesting assumption that in the future, corporations will still sell to humans and thus have to be creative to appeal to them. However, once AI weeds out the middleman – the classic consumer – and sells directly to other systems, there will be no need for attractive creativity.
The only job still valid in the future might just be philosophers arguing their case in favor for the human race with a superintelligence.
If I would teach anything in school these days, it’d be philosophy.
