Both easy and difficult problems can have simple or complex solutions. Two different axes of measurement.
Most problems in software seem to end up being harder than they look, so if I think something is easy I have to suspect I've missed something.
Most solutions in software end up being more complicated than they needed to be, because we don't have the hindsight to realise that until after we've done it and our managers are demanding the next thing.
Sure, but that's not really what the quote says, it doesn't talk about making things more complicated than they really are, it just talks about "complexity."
