You&#x27;re right, but you&#x27;re not rebutting his point, you&#x27;re actually reinforcing it: all of those things were possible in 1950, we just made them faster. The whole point of the post is that very little is completely new, meaning (close to) not understandable to a 1950 man:<p>&gt;  They will no doubt be impressed with miniaturization as an evolutionary spectacle, but will tend to have a context for the functional capabilities of our gizmos<p>You say that we can now face to face with people from the other side of the world in real time -- he says if there was as much <i>innovation</i> (and not just refinement) as there was between 1885 and 1950, we should be able to interact with a hologram of someone from the other side of the <i>Solar System</i>.<p>The real change a 1950&#x27;s man would see is probably how more linked humans are (mostly first world humans though) and how much more interaction there can be.
