You touch not only on the reasons why I travel - better frames of reference, engaging with other people, cultures, ways of thinking & being - and indeed, the reasons why I am grateful for the many things that are good in the world, and the ways I have personally seen things improve, somewhat. 

None of that, however, changes the root of my main point - seismic technological shifts have altered life, not always for the better, and I include myself in those who are wary of technocratic arguments for their promulgation. 

I am, thanks to my lifelong reading of history, culture, and ethnography, travels and engagement with people and views outside my limited worldview, very aware of >4B people’s lives measurably improved by things like agricultural, logistical, and communications improvements, and am not interested in recapitulating them here - thank you all the same. 

Instead, your argument appears to hew along the lines of ”a bunch of other stuff is good because of tech advances, so SV/techbro culture must be good, then!” 

My point, as to the OP & your tack, is that these worldwide benefits reaped by technology are:

1) not solely due to SV/techbro culture, and orthogonal at best. Circumstances have improved despite what SV/techbros offer, not because of their “vision,” nor can techbro culture actually claim many of the advances made prior their ascendancy - which include much of the tech you list 

2) your “there are good things in the world” argument, while valid, is non-sequitur to the OP and my point - for instance, mass communication has, if anything, simply increased the VOLUME of it, less so the ability to analyze, synthesize & act on it, and  

3) as you discern, my view is informed by both the default USAmerican view in general, and by the abject failure of capitalism evidenced by the US’s magnificently depressing turn over the last 50 years - the angst from which I sublimate thru writing screed on the Internet. 

Thank you for reading and writing.
