Hard to say that cloud storage and travel accommodations are not real problems. The solutions created with YC's help have improved the lives of hundreds of millions of people.

And you're not considering the recent increased YC focus on startups from developing countries. Just from top of mind you have companies selling cheaper solar energy in Mexico, improving online payments in India, lowering interest rates in Africa, treating low-income patients in Central America, etc.

There are dozens of YC companies just getting started that will positively impact the lives of billions of people in the next 10+ years.

I don't think it really is. These ideas have been kicked around for a long time and several companies have attempted at solving them.

I am not talking about execution but about problems as in. Solving the problem is the execution (think cure for cancer)

I am not saying there ren't companies in YC that aren't solving big problems but it's not what they are good at noor what the angel model is good at either IMO.
