I think some of the wordings that made sense circa 2021–3 are no longer the best wordings.

I also agree we should sell Scala 3 more.

Two things:

  1. You repeat "That said" two times, my formal English is not that good to think of alternatives, but maybe there are better combinators, like using However for the second part?

  2. Should we also mention LTS VS next? Maybe in another FAQ entry and link it?

oops, fixed

Should we also mention LTS VS next

Hmm, I'm not sure if that's actually an FAQ. It does sometimes come up, but my hope is that people are normally finding their way to Scala Next by default.

In any case, I think it would be a separate entry.

Regardless, you should choose Scala 3 unless you have a specific reason
to need 2. Scala 3 is the future, and it's the best version for
falling in love with the language and everything it has to offer.

They always say an "older version" is better for falling in love, especially your first time.


That said, many Scala jobs are still Scala 2 jobs. In most cases, the
cause of that is simply inertia, especially at large shops. (But it can
sometimes be due to availability of specific libraries.)

This makes Scala shops sound stodgy and cumbersome.

Many legacy Scala shops need a kick in the pants to upgrade. Since they are eager for young talent, you need only tell them that you're "only comfortable coding in Scala 3" to flip that script.
