The "Silicon Valley Model" in effect
1) Find some industry that has some room for improvement (in some way)
2) Persuade a bunch of VC investors to sink shed loads of cash in your plan while you corner the market (then you can dictate the prices yourself)
3) Do the bits that can easily be improved (phone app to access drivers, dodgy business practices to shift liability from Uber)
3) Pray to f**k that [i]someone[/i] can invent the rest of what you need (acceptable driverless cars in Ubers case) to make the rest of your cunning plan work.
Obvious flaws
1) What if there is no monopoly position because the market is (and wants to remain) fragmented?
2) The magic tech needed to complete your plan is impossible or does not arrive promptly?
Obvious answer. Tell the VC's "Que será, será. Shrug shoulders and say better luck next time boys" as you walk out the door with just your rather nice (protected) final paycheck.
