Here's a story to illustrate. Recently there was a headline about some project at MIT that used CRISPR to figure out the function of every protein in a human cell (or something like that, I'm sure I misinterpreted it in some way). I told a friend who is an actual biologist, and he said of course they didn't literally do that, that would be impossible. So I guess what they really did was.... something-something with CRISPR that gave information about a wide range of proteins in the cell, or something. They added a lot of facts to the library. But they marketed it as if they had made a huge stride towards understanding how the whole machine works. That gets people like me more excited. We'd like to know how the machine works and then use that to make it work better.
