      Hi yads25,

      Please use <code> tags to wrap the coding parts in your nodes.

      Can you please show us your sample file, so that we can give solutions without assumption.

[moritz]: depends on what you mean by "most stuff"
[1nickt]: I am sure I don't know about most of the stuff that is no longer controlled by humans. I do know that it's past the point of determining consumer pricing and into things that can kill me with blunt force!
[holli]: but is this really a problem 1nickt? Nobody knows how your human taxi drivers brain works either
