Satoshi wasn't wrong. Satoshi didn't know though that blockstream will derail bitcoin project on btc chain by turning into SOV with not working fee model and limited capacity.
BTC chain might be able to sustain itself longer even without mining reward, but at cost of huge fees. It is better to not exist for btc than become such a abomination.
Nine years to go. Still time to tell, but i think it's slowly becoming more clear that there were a multitude of factors that Satoshi did not and could not account for.
