I've been using Ruby for more than 10 years now, and I only started using LSP recently. To me it's a nice addition but I can live without it. Type is just one of the tools, not the only one imo. Not trying to sound negative but type is becoming more like a hammer analogy nowadays.
And it's not limited to Ruby. Javascript, Python, all similar languages. Not everyone is a fan of type. We won't reach consensus imo and that's ok.
