What the grandparent post means is that in dynamic languages you can just implement one of the "base" methods yourself instead of inheriting from a class that's bigger than you need, in order to avoid problems. I personally don't have an opinion on that, but it's not something I'd do myself.

Also, like the sibling said, inheritance is a tool that does multiple things: code reuse, which we call implementation inheritance, being the one everyone hates (the age-old advice is to use composition for code reuse instead), and interface inheritance being the one everyone loves.
