What's the difference between the usage and meaning of そもそも and もともと?
They both seem to mean something like "from the start/to begin with/originally" in dictionaries, but I believe their usage differs. I've seen numerous explanations by searching:
The accepted answer at this Chiebukuro page says that it's a difference of time for もともと and logic for そもそも.
This page says that そもそも, but not もともと can be used for expressing the essence of things or for criticizing other people, and that the former is subjective and the latter is objective.
Another page in that same thread says that もともと is the state before a change, and そもそも is used for how things come about/the essence of the situation etc.
While dictionary definitions for もともと and そもそも are very similar, I think the examples there are making me lean more towards the second explanation, but I think there also might be some other ways which they differ.
