Deconstructing a hype: What people think is wrong with Ruby?
summary
A research project collects roughly 25 interviews with core implementers, gem maintainers and organisers and finds concrete complaints: Ruby’s slowness is by design (developer happiness over raw speed), CRuby ships a JIT in 2.6 but still has the global VM lock so threads can’t execute Ruby code in parallel, processes duplicate memory so servers use multi-process models like Unicorn, JRuby has long startup times, and C extensions are the largest practical blocker to portability and memory improvements — plus Ruby 3’s 3x faster goal sparks debate.
