Yes, but... (Score 1)

...while the tech innovations of the past 50 years may be less significant than those of the 50 years before that, I think it's premature to assume that the overall pace is slowing and that there's less to be discovered. I agree that basic sanitation and such is more universally important than cell phones, but just think of some of the things which we as a society have not yet even considered. Maybe in 50 years AIDS and cancer will be non-existent. Or maybe we'll come up with some sort of Star Trek transporter. To say that inventions from 1900-1950 are more important than ones from 1950-2000 is a fair statement. To say that we've invented all the important things we, as a society, need to invent is foolish.
