Similarly, I don't get how people can see the rate of progress and take it for granted that it'll maintain the same cadence, or even accelerate.

We went from the first airplane flight to walking on the moon in about 60 years. We had regular supersonic commercial flights shortly after. Applying the same logic, we should all be routinely flying to Pluto, travelling in flying cars like in the Jetsons, and commuting from Sydney to New York every day like it's nothing.
