People thought that data is the new oil, but it turns out it's not. Data is the new uranium. Powerful, yet toxic and irradiates everything in proximity. You most emphatically do not keep large piles of it if you can help it, and if you do, you silo and audit the sh*t out of that to control access and prevent theft because the potential for abuse is very high.
I love the oil vs. uranium analogy. Uranium can be powerful and useful, but risky to hold, difficult to protect, and probably more of a liability than an asset.
This is exactly why I like to use this analogy as well. Being all naïve and starry-eyed about the potential of data without considering the fallout from its use belongs to the pre-GDPR stone age of technology.
