I did not downvote, but I don't think your idea about "all info will fit in a small space" holds up.
One problem is that sensor sizes are increasing at similar rates to storage sizes, for mostly the same reasons. Same goes for our ability to process data into novel forms, and in general to create new data.
Moore giveth, and Moore taketh away. Good for our line of work.
We started with language then writing, then the printing press then telegraph radio, and phones and now digital information.
We'll eventually get to the point where all of the worlds digital information will fit in devices the size of dice. And we're not far off either.
I actually do agree with you that we tend to rationalize our actions, but that's not some kind of epiphany.
Edit: If you're going to down vote the least you can do is rebut.
