@yora @jzillw robot vacuums. The most revolutionarily useful idea in the last years, if you ask me.
But other than that, yeah, we're kinda stuck. There are SSD's, they're like HDD's but somewhat better. There's also this revolutionary idea of flat rate public transportation, but it's only here in Germany. 3d printers are kinda good but only for their own use cases. mRNA vaccines.
I guess fascism is a thing nowadays, but that's neither new nor useful.
Not much innovation these days, huh?
