To be clear - I'm not saying that analytics and data engineering are a fad. I'm not saying the data teams are doomed to fade away, or that the old fundamentals of data modeling are wrong, or that the urge to quantify everything is a mistake. I'm saying that things seem pretty good, right now. But, you know. Like Charles Schwab constantly says, past performance is no guarantee of future results. So someone else might say all of that in the future - because, as John Maynard Keynes said, in the long run, we are all dead.
