Answers are easy. Finding problems are hard.

Anyways I am not sure if it is really easier to solve a problem than to find one. I would say the hardest part would be defining a problem in way that it is approachable. You can come up with a lot of very general problems, the hard part is narrowing it down.
However, convention on HN suggests that it's appropriate to copy headlines verbatim from the linked article. It's unclear what the appropriate behavior is.
"Sorting problems are easy, finding problems are hard."
And of course, finding problems is a finding problem. No wonder it's hard!
And don't blame me for the headline; I just took it from Venturebeat :-)
I stumble on good problems with no obvious answers frequently, and my take is that approaching them with the mindset of "hey, what if...?" is what is really uncommon. Not hard, children do it all the time.
What's hard? Keeping that mindset of "what if...?" alive over the years! :)
