Most disagree with Peter Thiel that "competition is for losers" & monopoly is good. Do STEEMers think decentralization is inevitable and will end duopolies like $GOOG & $FB in online ad revenue?

That's to say: most people accept the conventional "wisdom": monopoly = evil, whereas capitalism = perfect competition = good/progress/"don't be evil", etc.

"If you want to create and capture lasting value, look to build a monopoly," writes Peter Thiel in this provocative and well-reason commentary in the WSJ: http://www.wsj.com/articles/peter-thiel-competition-is-for-losers-1410535536

Alphabet (Google) and Facebook recently released Q2 earnings, leading to this AdAge headline regarding the combined $25.4B in revenue they just marshaled: "Digital Duopoly: Google Follows Facebook Results With an Amazing Quarter of Its Own"

So my question to STEEMers, most of whom I'd expect are at least predisposed to favor the kind of decentralization that STEEMit is built on (and is hopefully accelerating), is two-fold:

1. Is significant decentralization inevitable? Are we truly in the early stages of building Web 3.0, "the internet as it was supposed to be", and if so where will this have the most far-reaching impacts the soonest (and how soon)?

2. Whatever your answer to #1, will efforts like STEEMit gain enough momentum to take a significant chunk out of the duopoly rents described, and if so how much and how soon?

Of course, beginning to answer these questions opens up myriad more, such as

1. If we are building Web 3.0, who will be the people and entities (companies, groups, DAOs, etc.) who will have the biggest impact?

Have at it, people! I look forward to healthy debate BASED ON EVIDENCE BACKING UP YOUR POSITIONS.
