Most of these things are either likely to be fads (NFTs) or just ways to fuel the speculation and ponzi schemes (compound and uniswap.) Theoretically lending could be used for doing things in the real world I guess, but it seems like once the money is in crypto, it just sloshes around creating more crypto. The betting market is an interesting one, I hadn't seen that. IMO DAOs and DeFi are interesting, but I haven't seen it have a big effect outside of crypto yet.
