@feonixrift that said, there are certain situations where:
1. the amount of data is insane
2. there is a competent data scientist available to crunch it
3. one cannot go back to the source and ask them to "fix it":
> "hey, Monsac Fonseca, we got this bunch of data of yours from a whistleblower, but man it's just garbage! any way you could give us cleaner data?"
Watching a good data scientist apply machine learning witchcraft to that is a sight to behold.
But these are rare, rare cases.

Oh I don't doubt it. (I am one; I won't call myself a good one, but I dayjob this atm.)
