We can conduct the same science that any manned mission would do for 1/100 the cost, 10x better and faster, using robotic probes.

In terms of objectives related to science, that is true.

If we are to pursue "Space Manifest Destiny" goals (space colonization, etc.) basic technology will have to advance a few more steps to enable space resource processing at cost-effective levels.

The von Braun paradigm of space exploration is about to collapse under its own weight, IMO.

Manned space travel at the current time makes no sense scientifically, politically, economically or for any other purpose that I can divine. 20 years from now, that may no longer be the case. But at the current time, the cost is prohibitive and the benefits are nil.

Many years ago, I went to a lecture with one of the scientists who came over from Germany with von Braun.

He said the United States does not, and has never had a space program. What the United States has, is a space race.

That is incorrect. As you know, the Treaty is the main impediment to space development.
