I agree with you on both the "green technology" race and the fact that China has not only quite a bit of capital but also resources to develop intellectual property. However, I wanted to comment that in the US...if we are to compete technologically, it needs to start in the schools on all levels as it pertains to math, science, and engineering...teaching children, teens, and young adults to start developing technology..encouraging them to innovate. I'm concerned that schools are losing funding, teacher jobs are getting cut...who will lead these efforts? In addition, even though we are according to the UN the top manufacturing producer in the world, we are doing it with less people because we replace the labor with automation.

The race this time is with China in becoming the "green" technology winner. There is a lot of money up for grabs to the country that first develops the intellectual property.

The fundamental problem isn't an external enemy, it is us. . We have allowed 'our' government to perpetuate a government school system that specializes in behavioral conditioning: the brainwashing that somebody else's answer is more important than your own. Until we rise above that basic failing, our kids will continue to fall short. School is about gold stars and kissing @ss for grades, not about learning to think. . I was a fortunate one. My teachers didn't want to suffer my questions, so they sat me in the back of the room as 'teacher's assistant' ... where I watched my fellow students bulldozed into submission to the acceptance criteria. . It is time to dynamite this rut and those politicians who profit from its continuance (and that includes both Dems and GOP).

As a kid I tuned into that Sputnik "beep, beep" signal shortly after it was launched. Aside from the wonder of the overall event, it still just beeped, so a sense of "so what" crept in. The importance of Sputnik was what it did to the US efforts afterward as there were clear goals. Regardless of the vagueness of the goals in the president's speech, Rick's article comment vis a vis the political and economic realities being currently faced most likely will thwart many efforts.

While there were significant technological spin-offs, the primary motivation of the Apollo program was political: to make the Americans feel better than the USSR. The Apollo effort was achieved through nationalism with most of the people feeling they were doing a great thing for America while they also felt a threat from potential USSR nuke attacks. It is a lot easier to motivate nationalism and such efforts when formed up as a battle line against a very clear external enemy that can be beaten in a very specific race or battle with a specific goal and target. I doubt very much that the same basic approach would work now. Firstly, there is no clear enemy. In the 1950s/60s the USSR was a very clear enemy and kids practiced air raid drills at school. Now perhaps "We have met the enemy and he is us", but that does not sit well with nationalism. Perhaps China can be waved around as a vague trading "enemy", but nothing very clear. Secondly, there is no clear goal and race. Getting to the moon before the USSR and before the end of the decade is a clear and specific goal. We can mentally see a finish line with ticker tape parades etc. Long term growth and economic prosperity is not a specific goal. When are you "done"? What are the ticker tape parade moments? In short, trying to equate this with a Sputnik moment is just wishful thinking.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
