Up to now, declarative programming languages such as Prolog or ML have not been used for real-time applications. - Joe Armstrong

I always imagine a historian in 2 or 300 years' time writing the history of this period. It would just be like the Dark Ages, the ages of confusion. Will it end with computer failures that kill millions of people or will it transition into something that is for the benefit of mankind? We don’t know at the moment and I don’t know how long it will be before we know.

If you imagine the combination of petabytes memories with LiFi and communication at tens of gigabits per second but the combination and like 10,000 Cray-Ones and a little thing like your fingernail everywhere in every single light bulb that’s like an atomic bomb hitting software. What we’re going to do with it, nobody’s got a clue.

People are inventing new programming language all the time but I think that's not the big problem is actually writing programs. I think the big technical problem in building system is what I call "the connecting things together problem". It's a version nightmare problem. It's given things in different languages and actually connecting them together.
