Cryptocurrency (or more specifically, cryptographically enforced consensus networks) are way more of a technological leap than voice interfaces connected to the internet. If there's a top invention of the 2010s, it's bitcoin.
Cryptocurrency is actually a technological leap without much precedent (it's sort of similar to bittorrent and some of the ideas were in the air, but no one synthesized them into something useful prior to Satoshi). I think it's still an open question to what extent it matters long-term. It's mainly used for speculation and facilitating illegal transactions currently.
I think we're talking past each other a bit. I think there are technological leaps and sociological leaps. Most new tech is a sociological leap: it changes society but it does not make use of anything radically new.
I think the only real technological leaps in the past twenty years have been maybe crypto, and some things happening in biology. Notably absent is renewable energy, which was largely developed many decades ago but is now being commercialized due to process improvements.
Streaming, which you mentioned is a big one too. I know it existed before, but it really took off then. Zoom might fit into that category as well.
