When was your experience? I could definitely agree with that pre 1.9.x. But I can think of barely a handful of examples in which minor things have broken during my time in Ruby from 1.9.3 to 2.1.5...even when booting up a year-old laptop with godknows what actual version of Ruby via rbenv I have on it...things just seem to work...And even problems that arise from specific scenarios with libraries, or when I simply must move an old system from 2.0 to 2.1.x or whatever...Upgrading the Ruby and then running bundler almost always just works.

In contrast, with Python, on a weekly basis I run into 2.x and 3.x problems...last week it was running the Google Cloud SDK, which is 2.x only. I say this as someone who has almost switched exclusively to Python (3.x) and enjoy it...but man I miss the days of Ruby's ease-of-use.

(but yeah, 1.8 to 1.9 was not a lot of fun, but thankfully, many years have passed since then)
