I definitely recommend using Ruby, and Rails.
The Jason Fried and David Hansson Musk/Fascist vibes are real and are a problem. Most of the people in the Ruby community recognize that problem and are taking steps to mitigate that issue. Most of the core Rails committers don't work for 37 signals, and it's not really a thing made just by them.
Definitely use Rails to start a new project. The real hero here is Ruby and the Ruby ecosystem. It's incredibly stable and mature, But also getting faster every year. About 20 years ago Ruby web frameworks agreed on an ad hoc server interface api, Rack, which is one of the secrets that has made Ruby incredibly stable.
The package system, Ruby Gems, is really great. You can find a Gem for just about anything you could ever need or want. With mountains of Open Source projects and code to read to pick up patterns, or to see prior art to solve a unique problem you're encountering.
Anyways, it's a really solid choice.
