We're in one of the biggest tech bubbles we've ever had.

I think mobile web enabled services can be great business but A): it doesn't apply to everything, I think the markets will ultimately get a bit fragmented when the crunch stars to happen. And the other thing is, B): it doesn't necessarily work with everything.

For venture capital, one of the original principles is people you want to invest in are people who've done it before with someone else's money. Not people who've just came out of business school.

Everyone who is inside of an expanding bubble can't imagine another world where the bubble collapses on them. It's unimaginable because they haven't lived through it.

Venture capital has peaked in terms of its appetite, in terms of how much money it wants to put in. So now private equity funds are piling in. Primarily because interest rates are virtually zero so there's no fixed income play and they're not moving around.

How many of the unicorn companies are really prosaic businesses - like limousine services or renting rooms in your house? The original VC firms from the '70's made their money and established the reputation of their respective brands by leveraging big cleverness with small capital, not small cleverness with big capital, and that's what's going on with these unicorns. That has never worked and it won't work this time. It doesn't produce venture quality returns, and it never will.

A lot of the philosophies of the businesses are just 'we're interested in getting customers now and if we're losing money with each customer now that's okay because we have this huge hoard of venture capital that we can subsidise the operation with and once we have the required number of tens of millions of customers and we drive our competitors out of business, then we can start to raise prices and become a proper business.'
