After all, human being the designer of the AI, everything the AI does (thinks, calculates, ponders, measures, decision making, everything) it is a poor copy of human thought process
Everything a human does is limited by our biology, there is a limit to how quickly we can be trained, with more advanced subjects taking ever longer to understand. For example, whats the average age to acquire a PhD?
There is a limit to how much information we store for processing, and a limit to how quickly more information can be fed in.
The beauty of an AI system is the system can be designed from the ground up avoid the restrictions we have. Even if it were true that human's couldn't create something smarter than us, we certainly can create something which matches our intelligence but without the hardware restrictions we have ourselves.
2. There are two reasons why America's work force has gained skill at a slower rate than in the past -- A. The new immigrants to America are simply not as smart as the immigrants that moved to America decades ago Previous waves of immigrants to America came from Europe Current waves of immigrants who land on American soil came from Latin America and the Islamic countries
Bollocks, the first waves of mass immigration into America were from Europes poorest groups, low education, subsistence farmers in a lot of cases or groups with poor relationships to local authorities for whatever reason.
I'm not sure how you plan to measure the gain in skills between people now and then, unless there were lots of scientific studies conducted back then to record how long a new skill takes to learn which can be repeated now.
