Some great points and examples being made. We are indeed still in the early phase of tech. Marketing is indeed unrightfully being forgotten when looking at digital advertising as a percentage of total ad spend. Online shopping curation – as opposed to logistics – is just getting started.

Investing implications/call to action: which public companies should capture some of the value of this opportunity, parts which are often forgotten such as shopping curation and marketing spend (largely confined to offline today)?

It seems this is a simple bull argument for digital ad duopolists FB, GOOG: well positioned with undemanding valuations.
