I am sorry you were downvoted (particularly because you were called a shill for daring to voice your reasonable opinion). There is a doom-and-gloom mentality on this site; people seem like they want the end-of-days. I noted, as you did, that almost all of the problems listed were independent of communications protocol.

This entire argument is one of "exaggerate the bad and completely ignore the good". We have companies working on cheap space travel, which opens up asteroid mining (mitigating resource crunches) and allows us to use space-based resources to alleviate problems on Earth (solar shades to reduce warming, etc). Asimov made a great point at the end of I, Robot, where he notes that the intractable problems of one age are rendered moot by the technology of the next. People feared that NYC would be uninhabitable by the year 1950 because there wouldn't be enough place to put all the horse manure - which became a non-issue with the advent of automobile. People feared mass starvation in the 1970's because we couldn't produce enough food - made irrelevant by the green revolution. People fear global warming and totalitarianism today, and it will be made irrelevant by the tech of tomorrow. We already see birth rates falling globally, to the point where we will soon be shrinking in population. This will reduce stresses from unemployment, and paired with a burgeoning space economy we will have more to share with fewer people.

There is no reason to cower from the ills of today; they are only a call to keep moving forward.
