So far I have not seen any cryptocurrency systems I consider to be good, so if I was to take that "evidence", then my conclusion would be that there is no one worth talking to at all.

That's fair, but it's also a bias. The question then is: what if your assessments based on what you consider "good" are wrong? You taught us that engineering is all about tradeoffs. Is the market wrong? Also, what if you are right? What should we prioritise as we build?

You are arguing my point for me. The goal of these interviews is to gain perspective. That is why I _didn't_ create a ranking like you suggested, to avoid bias in the first pass.

Would you allow me to give examples of why you need better interlocutors? 1) You mentioned the problem of irreversible transactions and were given a strange answer about a hypothetical protocol yet hash-time-locked-contracts already exist in Bitcoin:https://docs.lightning.engineering/the-lightning-network/multihop-payments/hash-time-lock-contract-htlc …

2) You mentioned (perhaps tongue in cheek?) the "problem" of sending to the wrong address: This, in practice, is a difficult mistake to make e.g. by typos, because bitcoin addresses have inline checksums and your wallet will refuse to send: https://learnmeabitcoin.com/technical/checksum …

3) You mentioned the oracle problem and how on-chain contracts can't enforce real-world contracts. But we do this every day using over-collateralised multisig on-chain escrow for large and small amounts of money: https://hodlhodl.com/pages/faq

No, you do not, because it is mathematically impossible. The two generals problem is unsolvable, and is proved unsolvable, so off-chain delivery of goods can never be "handled".https://en.wikipedia.org/wiki/Two_Generals%27_Problem …

I am trying to provide an example: I and many others take delivery of real-world goods using multisig escrow to align incentives. I'm not talking about mathematics but practice.

Yes, but the practice is just that: it's a social practice. Blockchain offers nothing new here. It has all the same problems as existing currency, with nothing to add. That is the point.

Remember the context here is "does this do anything our current banking system doesn't do". In order for that to be true, the government must not be a crucial actor. If they are, we're back to the same system, regardless of the underpinnings.

The point of this line of questioning is to emphasize how, whether you like it or not, the two generals problem ensures that you will need a third party to enforce off-blockchain activity, because there simply is no other way.
