What's next?  You probably see all this, and then you get frustrated that “data science” is hard and that the only “solution” is “machine learning”. That's OK. So let's start with a quick reminder that there are many approaches to time series analysis. But there's no one-size-fits-all approach. We need a good understanding choosing and use it. We need to select the right algorithm for the job. Furthermore, we are still using the “time series analysis” paradigm.
