I've had discussions with some friends of mine on similar topics. I sense that some of the old Internet guard yearns for the days when they were the darlings of the investors and/or research funders. Part of the difference between now and then (especially back in the 1960s) was that there was generally more optimism in the US as a whole, particularly with regards to technical advancement. I also think there is a sense that that aspect of Internet development is done, but more work is needed on applications and services.
There's more to the book. JE weighs in on the "shortage of qualified tech workers" debate, on the side of those who want to see visa caps raised to allow more non-citizens to fill US tech jobs. I'm disappointed to see this – certainly, she must be aware of the many talented people who've lost jobs and struggle to find jobs, while people enter the US on work visas due to a supposed shortage. I'm concerned that there will be increases in visa caps after the November election – McCain and Obama both support them, and the number of respected tech pioneers/entrepreneurs/veterans who advocate them continues to grow.
