I was programming Prolog []... What happens when a Prolog program goes wrong? it says no. There "no" is not a very good error. Core damage is much mo… - Joe Armstrong

One of the things which worries me is the silly idea with the cloud. If we just store everything in the cloud, the unintentional side effect of that is we will probably lose all our history. And I am kind of worry to life. two hundred years time and look back and say just sorry, we just lost all the history of the last twenty centuries.

Instead of handy compose, we'll keep compose exactly the same and will write a little function which takes a function that does not have debugging and return the function that does debugging. And we have a function that accept only one argument, the un-debugging version, we'll add another little function that automatically add an argument to it. When we done that, we can bind call compose on it and everything will work and will be nice. And will be peace on the earth and everybody will have a good time.

I think we seem to have forgotten that things can be small. This way of decomposing systems into small things that I can reason about.
