Uber is now too big to fail. Possibly the most important company this decade. I never cease to be amazed by their phenomenal execution across the world.<p>I was in Mexico City last week where I truly came to understand the enormous impact Uber as a company has had in these past few years. The service was highly prevalent, popular, and the experience was completely seamless — just like in the US. It barely skipped a beat. Their execution is likely a prime business case study in that no other company has built a technology business that has a huge, real-life logistical component this fast — and in dozens of cities around the world, spanning an equal number of ways of doing business and cultural barriers.
