I'm one of those people. :) Well, it's not so much that I prefer no explicit types, I just dislike how most languages require you to specify them, and to do so at the least opportune time, so I end up preferring languages that don't require them at all. (Ideally, the language would let you start with none and then layer them in as the design gels.) FWIW, there are definitely ways to do it "right" in languages like Python, but it's a slightly different approach to dev than in other languages, so people create a mess if they don't shift, or if they are just untrained/sloppy/lazy/whatever. But when you have a team of people doing it right, it's really quite nice, even as the codebase grows large. But if even just one person on the team can't be trusted to do it that way, you're probably better off in some other language.
