What people used to like about Rails, those haven't changed and it is also much better than before. ( Would still want more on Auth )

Hotwire, with Turbo. It has been improved and used in production for quite some time. This also got boosted a lot with JS front end fatigue.

Performance. Even by default Ruby 3.4 is quite a lot faster than 2.x era. But with YJIT it is in some cases nearly double and ~30-50% faster in Rails.

Whatever performance issues there used to be? We will have 256 Core Server in next 12 months, or 512 CPU Core in Dual Socket Setup. CPU Core is getting cheaper and faster.

I always like to say Ruby is the only Top programming language that doesn't have a big tech backer behind it. And it only recently found one. Shopify could now single handedly sustain the whole Ruby Rails ecosystem. It also means the whole ecosystem gets a lot more resources than it used to. ( YJIT is from Shopify )
