I will never ever make any statement about performance that is not based on measurement and I will never ever advise anybody on how to write their code without saying write it and measure. I just will not speculate. I think people who do speculate about this should not speculate about it and they should write it, run it and measure it.

you can basically make things as reliable as you by having lot of machines.

We wanted to build big distributed systems, fault tolerant systems. The sort of systems that everybody wants to build today. It's not just about telecom. At the time it was just about telecom but now, it's not just about telecom. Virtually, every big systems you want to build has to do these things. You want to connect millions of people and you don't want if the system fail in anyway, you don't want these individual transaction to be broken. We started to working on that, way back. That sort of way we got Erlang.
