I generally agree that there is no substitute for experience running in production and more data is better - or at least should be, if you can figure out how to take advantage of it.

The thing is, when it comes to weird events, historical data can't be relied on either. The next weird thing may never have happened before.

Predicting the future is hard no matter what you do. Gathering more data and learning more efficiently from what you have are both important. Training on artificial challenges can also be useful.
