Cryptocurrencies and their associated boom-bust market cycles are here to stay.

95% of blockchain development happens on Ethereum, and Ethereum is growing well, https://medium.com/@jjmstark/the-year-in-ethereum-2019-24201..., so the idea that there was a cryptocurrency era that's ended is not true.

Given that the number of 51% attacks has been quite rare and relatively low impact so far, I'd argue that your skeptics are still winning the argument. Far more problems have come from security failures outside of the cryptocurrency itself or predatory practices.

You misunderstand what I'm saying. They were skeptical of the attack vector I highlighted.
