Large projects, at least 4 years old. "I will also throw in the fact that doing software library version upgrades on dynamically typed systems is a pain in the ass." This is very true, but you gain a lot with dynamic languages in other areas. The last company I worked for had about 300 programmers in the office I was in. Roughly half did Java and the other half did Ruby. I was one of the few that moved between both ruby and java projects. I did not see these great benefits of static typing that people always insist exist for large teams at large companies.
