Which rather underscores the point that idiots investing dollars today in pie-in-the-sky schemes like asteroid mining are most assuredly throwing their money away.
I think the better way of saying this is that it underscores the point that obstructionist idiots have held back progress substantially because they are incredibly short sighted, and we should have been to that point decades ago.
We went from cars to landing on the moon in less than 60 years.
It's now been almost another 60 years. What significant progress has been made, while you idiots are all wasting time oppressing and shooting at each other?
