I'm really hopeful that invention, like the ideas represented on this list, will get more attention and excitement from our youngest and smartest minds. In fact, I believe that having a successful society is dependent on this.
But consider what it means to make money. Suppose you invent technology whereby those people doing their things most of the time can become twice as productive. They would be eager to pay for this benefit, and society has gained far more "value" by your definition as well.
Yet it's good people who assure the conditions under which invention is even possible.
There is a recall here in Canada for non-medical masks that have graphene contamination in them, it may cause lung damage. So there's that.
That's wild, but the more I think about it, the more I wonder if there's really all that much we don't know about how to transplant a head onto another body, if it's just to keep the donor alive (that is, what we don't know may not stop us from being successful putting a second head on to someone and connecting the blood supply so the brain survives).
So much for my weekend...

It takes a while for a new technology to spread to widespread adoption. For example, the 2007 launch of the iPhone lead to a decade of mobile adoption a few years later. But it seems there's been no new tech paradigm shift lately that's equivalent to the massive influence of previous innovations. Or at least I'm not seeing it yet.
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.
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.
Remember: The S in IoT stands for security.
Where do we put really good batteries? Lyft? Amazing phone cameras? Quadrotors? Fitness trackers? In ten years it will be clear where to place those.
Vinyl records! That's what should have been there. The LP was introduced in 1948 and the 45 in 1949.
Like, say, electric cars in 1900-1915?
Wikipedia is decent for a quick overview of a certain topic; but "boy oh boy," is it useless for anything of substance and depth.
All of these technologies, merely glossed over. Many, perhaps, even complete bunk with no realistic applications or time-frames for usable prototypes, all mixed in together!
Junk food for the mind.
