As an example, today&#x27;s cars are radically different beasts compared to what we had in 1950 (or even 1980).  They&#x27;re safe, faster, lighter, and full of subtle drive-by-wire algorithms and technology.  And there&#x27;s a huge amount of science and engineering advances that made that possible.<p>While I agree with his broad point that in-your-face radical advances are on the decline, there&#x27;s a lot going on under the hood that&#x27;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&#x27;t look any different.
