Who creates value in the art market? Is it the artist who creates the work? Or the dealer who persuades the buyers that the work has value? As a builder I’m attracted to the fantasy that I can create value with my bare hands just by writing code (or telling the AI to write the code), without needing any of those horrible slimy people in suits to build a business around it. Rock n roll man. If you build it, they will come. Is that the reality though? Or just survival bias based on the fact that a few geeks got lucky during the original dotcom boom when they had no competition from actual businessmen?
you can create value by preventing damage in the future, this will get rewarded by the ecosystem itself. That's really hard to describe, but you can try simply removing a danger or annoyance in an ecosystem like your hood or local park then be attentive about what will be better in your own life.
Art creates value with measurable 1.9x in my country, its studied and thus gets funding because they know every 100€ funded will create 190€ of economic value. This means if you give an artist 100€ doesn't matter how - the local economy will grow by 190€. Magic? Well it's just many soft factors - higher quality of life leads to more educated and productive people!
Understand these are all tools to make more of WHAT IS ALREADY THERE and has nothing to do with extracting resources and selling them or bartering. I think your dotcom bubble is an extreme with no value for general advice.
