Reference #1 Page 29 Paragraph 3 continuing to Page 30

Section: Recolonization by Nature

In this section, Dr. Dartnell reviews the processes that cause deterioration of built structures.

The paragraph that begins: “The greatest threat...”

continues review the natural forces that go to work to destroy structures built using this material, and describes the likely fate of most of them without constant attention by appropriate counter forces. In this case, Dr. Dartnell brings focus to foundations, and the effects of water moving unchecked into and around them.

It would be interesting to compare longevity of built structures in temperate climates with that of built structures in arid regions such as the Middle East. Quite possibly natural flows in those regions would have pronounced effects. I'm thinking here primarily of sand, but as Dr. Dartnell points out in paragraphs just ahead, climate change may increase amounts of water in those locations.

Reference #3 Chapter 2
Title: The Skills of the Unskilled
Section: The Broad Reach of Technology Specific Skills and Knowledge

Chapter 2 section Pages 30-34 introduces Mr. Bessen's personal experience starting a small business offering computer software.
This statement sets the stage:
Begin Quotation:
The biggest shock I had in starting a software company was just how important informal learning is.
End Quotation.

In the context of Dr. Dartnell's recovery scenario, it seems likely that almost ALL learning will be informal for an extended period.

On page 33, Mr. Bessen says:
Begin Quotation:
Learning through experimentation is also an essential part of science, and highly educated scientists acquire critical knowledge through experience.
End Quotation.

On page 34, at the conclusion of this section, Mr. Bessen says:
Begin Quotation:
In summary, a wide variety of evidence suggests that learning by doing plays a large role in today's economy.
End Quotation.

In Dr. Dartnell's recovery scenario, it seems to me reasonable for leadership to encourage learning by the individuals available, with a view toward success of the group undertaking.

Reference #1 Page 20 Paragraph 1

Section: Recolonization by Nature

In this section, Dr. Dartnell reviews the processes that cause deterioration of built structures.

The paragraph that begins: “So within just a generation or two ...”

sums up Dr. Dartnell's anticipation of what would happen to urban city landscapes over a number of years. While re-reading this passage, I was struck by the similarity of this vision to the reality of South American cities reclaimed by the jungle. The recent news (in 2018) included reports of use of instruments using a technology called LIDAR to reveal built structures hidden for centuries if not thousands of years by the jungle canopy.

Reference #3 Chapter 2
Title: The Skills of the Unskilled
Section: Turning the Tide

Chapter 2 section Pages 35 and 36 wraps up this chapter with a reprise of the importance of “learning by doing” in the United States during World War II, when a presidential directive led to construction of Liberty cargo ships.

Begin Quotation:
...average assembly time per ship dropped from 186 days to as little as 19 days.
End Quotation.

In the context of Dr. Dartnell's recovery scenario, achievement of performance gains like these by survivors would go a long way toward increasing chances of success.
