Well, in case you missed it, one of the best presentations on Bitcoin Atlantis. (see:

Kudos go to Jack Mallers, who explains how important was for Satoshi to create bitcoin's own time.
He goes for the argument that without the right difficulty adjustment people were incentivised to create more and more blocks in a given time window, thus speeding up bitcoin's clock. That said, bitcoin would eventually run so fast, nodes had a hard time agreeing on transactions due to physical limitations on data transfer speed.
Mallers points out that PoW and the difficulty adjustment are together the solution and even says: "This is why Solana and other shitcoins don't work"
To my understanding, most non-PoW blockchains have their own take on difficulty adjustment though. If you share the views that most other blockchains are destined to fail, please explain like I'm five why verifiable delay functions or other cryptographic takes will not do.
