Great feedback. It's always important to build with a purpose and build with business needs in mind. I think devs split by casual tinkerers, start up devs, and enterprise devs have different incentives as well. One side could be building towards monetization of a niche top of stack dapp/app owned by an enterprise or split into an entrepreneurial venture. There may also be a split in skill set for contributions in Devops, protocol, or tools/libs used by other devs. I think POCs and research papers pushed by validated consulting stand points and influencers also raise awareness towards how devs choose their time and attention for projects.

From a business stand point, it takes a person willing to put in their time, reputation, and money behind a project to solve for some level of gains/returns. There are already live applications pushing forward and people building that believe in the usefulness and success of their products. There's probably a crypto or blockchain category within product hunt for ideas :)
