We don’t even know this problem exist. How do we know it is even needed? How do we get to a better state with these unknown unknown problems?

My co-worker Michael L. wrote an internal page about how he thrives on these type of Unknown Unknowns problems.

I’m reminded recently that I get a lot of my energy and fear from unknown unknowns, because they are the most interesting ones, but also very likely to fail.

This is quoted from his internal page

- Known Known — I know exactly how to do it.
- Known Unknown — I don’t know how to do it but I am sure it can be done in some way.
- Unknown Unknown — I don’t know how to do it and I have no idea if it can be done.
