David Dalrymple, a researcher at the Massachusetts Institute of Technology, thinks human memory will no longer be the key repository of knowledge, and focus will supersede erudition. Quote:
Ignacio Rodriguez
Before the Internet, most professional occupations required a large body of knowledge, accumulated over years or even decades of experience. But now, anyone with good critical thinking skills and the ability to focus on the important information can retrieve it on demand from the Internet, rather than her own memory. On the other hand, those with wandering minds, who might once have been able to focus by isolating themselves with their work, now often cannot work without the Internet, which simultaneously furnishes a panoply of unrelated information — whether about their friends’ doings, celebrity news, limericks, or millions of other sources of distraction. The bottom line is that how well an employee can focus might now be more important than how knowledgeable he is. Knowledge was once an internal property of a person, and focus on the task at hand could be imposed externally, but with the Internet, knowledge can be supplied externally, but focus must be forced internally.

IMPACT evaluation system defines 50 percent of all teachers in grades four through eight as ineffective or minimally effective in influencing their students' learning. And given the imprecision of the value-added scores, just by chance some teachers will be categorized as ineffective or minimally effective two years in a row. The system is rigged to label teachers as ineffective or minimally effective as a precursor to firing them.
