If you cut down a tree, cut it in boards, cut the boards and nail the pieces into a bunch of chairs, that is value added. It did create wealth.
Same, if you write a bunch of code that did not exist before, and the code is compiled and linked into a program that allows users to do stuff they could not do before (or could, but much more slowly) then there is value added. Wealth was created, even if there is no physical representation of that wealth... but it has real effects on the real world.
But when people just place bets, and double-down bets, and triple-dare-you bets on whether or not some random guy is going to write a program that might or might not go viral and get a billion or eyeballs... that's not wealth creation. That is just toying with numbers. You just produce noise in the economy so that the real prices of real stuff cannot be discovered anymore.
