Are we in an era of technological stagnation?

We're witnessing an explosion in the capabilities of AI and just witnessed the fastest vaccine development and the first deployment of mRNA vaccines. Since the release of the iPhone we've seen continued improvements to computing power, HD video streaming become viable, the adoption of UHD technology, massive improvements in electric vehicles, and ground has broken on the first long distance maglev line.

We're literally in the middle of inventing cars that drive themselves and run on electricity. How is that not as big an invention as the iPhone?

to be fair, we have had electric cars for 120+ years

But their major improvements still contradict the idea of "technological stagnation"
