Vitalik: The expansion of the blockchain community should not be confined within the industry, but should focus on a broader external field

Vitalik Buterin stated on the X platform in response to other users that expansion is a good thing, but why does it have to be other blockchains? Why can't it be non-blockchain decentralized spaces, as well as open-source biotechnology and so on. I would rather see five different blockchain communities expand their interests more broadly than a single 'crypto community' with strong internal cohesion but no external understanding or influence.
