It's funny to see all the replies missing the point. I agree there have been few "step changes" in the way we do things. The biggest real one I can think of is the capabilities of small motors, that enable things like drones and battery power tools. But not a step change, just an incremental improvement. People had high hopes for mRNA, (no doubt people will take this the wrong way) but so far it seems to have been way overhyped. That kind of thing - the ability to arbitrarily protect against viruses - would potentially qualify. Overall I think the world is in decline progress wise, even as we make incremental gains in previously discovered tech, we lose e.g. Concorde or moon landings or even open borders. And soon the availability of internal combustion engines to the masses if elites have their way. Other than the neotlithic and industrial revolution, humanity has mostly languished. We could easily be in for more of that.
