As an example, today's cars are radically different beasts compared to what we had in 1950 (or even 1980). They're safe, faster, lighter, and full of subtle drive-by-wire algorithms and technology. And there's a huge amount of science and engineering advances that made that possible. While I agree with his broad point that in-your-face radical advances are on the decline, there's a lot going on under the hood that's easy to miss. Taking that to an absurd extreme, if we all suddenly became immortal, it would be a huge advance, but we wouldn't look any different.
