Whenever I teach people time series forecasting, I always point out that one of the biggest challenges is that you will always have values at prediction time that are out side the range of values observed during training (specifically the value of t).

I don't get this, time is usually not a covariate in ts models, so why is it a challenge?

This is a bad case of whataboutism (I hate this word but it describes the answer you gave), what do you mean by accelerating understanding? Maybe they are good as suggestion engines, but it is very early to state what you did.

Language learning: I have a couple of languages that I want to focus on this 2026. Both for the enjoyment of learning and using said languages, and also because it will help me improve work-wise.

May I ask which languages are you talking about here? and what methods you will follow?

we haven't really had time to take a breath and understand what's going on.

The field of Explainable AI (or other equivalent names, interpretable AI, transparent AI etc) is looking for talent, both in academia and industry.

That book doesn't really teach the tricks of the trade (and it is not promised anyway), but it is a good introduction to the world of memory for people unaware of the potential of memory.
