Look at what's being used in production. Job sites are great for this. Europe seems ahead of the curve because they work shorter hours, so they can't just pick technologies willy nilly. They need something that is immediately effective and saves time. Germany especially, as they have the Rocket Internet culture where they have to execute fast.

I picked up things like Kotlin and MVVM from those, years before Google adopted them.

Wait till you start seeing articles saying "Don't use X, use Y instead", and then look at what X does.

At the pace of most things in this industry, it might actually be somewhat usable/mature by that point.

I mostly read this site.

I also listen to what my company is telling us, because at the end of the day I have to listen to whatever they decide is the trend that they want to follow.
