I've seen pro blockchain cultists argue all day, but the arguments were the same 10 years ago...so no mental gymnastics..
what are some examples of some successful current uses of blockchain?
Successful = The firm abc uses blockchain to do xyz.
Not Successful = startup built another facebook "BUT ON BLOCKCHAIN"
2. Registry Services - ex. ENS, Handshake
3. Decentralised Lotteries, Decentralised Betting
4. P2P communications - libp2p, https://status.im
5. Decentralised network layer - https://protcol.ai, IPFS
6. Ondemand graphics compute engine - https://golem.network
7. Decentralised, permissionless LoraWAN - https://helium.com
8. Decentralised, trustless code execution and secrets management - https://renproject.io
9. Financial applications - DEX, Swaps, Decentralised exchanges
10. Certificate issuing - https://kryptomoney.com/indias-sp-jain-college-issues-degree...
11. Instant, global, zero permission access to financial services
12. Flash loans - https://aave.com/flash-loans
13. Kafka like streams, but decentralised - https://ceramic.network/

That being said I think we are not there yet. I doubt if there is a "destination". P2P systems trade speed and control for resilience and censorship (sorry for my dumb definition).
But 10 years is a short time span. Internet took more time than that to mature.
