The other thing you have got to do is take the data out of the cloud and put it into your home cloud. Make your own home cloud. - Joe Armstrong

The spec does not tell me what to do. What do I program? [...] I thought this is crazy, we are building products with specifications and things, and the specifications doesn't say what's supposed to happen. Then when you get to this point in the code where you don't know what's going to happen, everybody knows how programs it. I thought that's crazy because I didn't know and I thought everybody could interpret that differently and they could make an ad-hoc decision. So I thought to myself, the only sensible thing to do is crash. We just crash this call because we don't know what to do.

I wanted to build fault tolerant systems and pretty soon I realized that you can’t make a fault tolerant system on a computer, because I think in the entire computer might crash, so I needed lots of independent computers.

In Erlang, you have as many processes you want. You can arrange the processes observing each other. If you have got half million processes to do something, what is it matter if few thousand of them fail?
