Nowadays I am pondering whether Silicon Valley is guilty of similar practices.Read up on John Michael Greer's concept of "catabolic collapse":

I find a great deal of parallelism between Greer's observations and Marc Andreesen's "Software is eating everything". The two great economic sectors of the past 20 years in the US have been the FIRE industries (finance, insurance, and real estate), and software / IT.
Broadly speaking, a society facing the end of an anabolic [growth] cycle faces a choice between two strategies. One strategy is to move toward a steady state in which C(p) = M(p), and d(R) = r(R) for every economically significant resource. Barring the presence of environmental limits, this requires social controls to keep capital stocks down to a level at which maintenance costs can be met from current production, and maintain intake of resources at or below replenishment rates. This can require difficult collective choices, but as long as resource availability remains stable, controls on capital growth stay in place, and the society escapes major exogenous crises, this strategy can be pursued indefinitely.
The alternative is to attempt to prolong the anabolic cycle through efforts to accelerate intake of resources through military conquest, new technology, or other means. Since increasing production increases W(p) and increasing capital stocks lead to increased W(c), however, such efforts drive further increases in M(p). A society that attempts to maintain an anabolic cycle indefinitely must therefore expand its use of resources at an ever-increasing rate to keep C(p) from dropping below M(p). Since this exacerbates problems with depletion, as discussed above, this strategy may prove counterproductive.
Yes, software provides efficiencies, and some of the recent chain of startups (Google, Twitter, Facebook) have succeeded in ephemeralizing knowledge, communications, and networking in ways which, to an extent, increase social interaction, but they're doing so at the cost of a highly confounded signal/noise ratio, and with significant externalities.
Then there's the whole "moving financial capital around" aspect of tech funding and investment, which I'm coming to increasingly question. I don't find it particularly productive. The number of firms whose exit strategy is "get bought by Google / Facebook / Apple" reminds me strongly of the late 1990s "get bought by VA Linux" (remember them?).
And for perspective, I'm in my mid 40s and have seen a few cycles so far.
