I don't see how you can say this. The 2 most valuable tech companies started in the 2000s are Facebook and Google. Those 2 companies are glorified Ad Companies that happen to provide a service so they can aggregate data to sell more ads. Other than organizing the information of the internet (lately it is debatable as to how well they have been doing this lately) via google, what value addition would you say facebook or google is providing? Same thing with Uber, now that VCs are no longer subsidizing Car rides for the entire world, it's just a more expensive cab. What are the tech ventures that have been adding value addition to society. Based on the experience i've had with family members becomes complete Q psychos i'd say net negative on facebook's part and they dont even build anything.
