masslessness

I'm a keen follower of the tech scene, especially all the great stuff that comes out of Silicon Valley and the rest of the world. Something that puzzles me is the sheer volume of projects and startups that are launched and receive funding.

Surely not all of them are able to generate any sustainable revenue that is long-term. What's the value to the creators therefore who sink countless hours into creating them and to investors who pour in so much money?

There's only so many consumer eyeballs and wallets in the world, it almost seems the supply of products and services is unimaginably over supplied to a fixed demand? Or is that the wrong way of looking at it?
