While some data science tools may be `excel-implementable` (or some equivalent) in five to ten years, there's significant risk of mis-implementation of results given how much of a mystery many methods are to the people who'd use them.<p>I'd compare data scientists more to CPAs. You can have software like TurboTax and Quickbooks, but CPAs don't seem to be going anywhere. Similarly, anything that's more complicated than cookie-cutter data analysis will require someone who knows how to develop, build, and debug the algorithms themselves.<p>Use cases of data science are often too specific for most data science to turn into button pushers. Look at the vast array of ways a neural network can be implemented. Which one of those implementations will be in the `excel package`?
