Who needs blockchain/web3?

A recent post by Dan Thomas on LinkedIn brought up the issue of the usefulness of blockchain, web3, NFTs, etc., and touched on the question of decentralization and blockchain trilemma.

Any sign of sobriety during this intoxicating crypto frenzy is a good thing.

I partially agree with the original post, especially the point that many of the incumbent businesses shouldn't be excited about DLT and Web3 because, as the author points out, a lot of things they want to do can be done more efficiently and more economically using conventional database technologies.
