Does this signal the eventual end of all blockchain endeavors? To me, it makes bitcoin look very cumbersome. Are there potentially other distributed ledger technologies yet to be discovered that will make blockchain and hashgraph look like dinosaurs?

I don`t think this will mark the end of blockchain technology. It marks the beginning. Remember, the telegraph made way for the telephone and ARPANET turned into the internet. We are seeing a developmental phase in quantum computing that will revolution the internet.
