I don’t think they are solving the same problem, no, though they may say so, even believe so; once we move beyond appearances, see how their trees inevitably grow, the fruits they inevitably bear, mere variations in perspective simply cannot account for half of it; still, and so much for well worded, “goal” would have been a better choice to convey my meaning, though you might not consider it much of an improvement. My point remains, however; I don’t think you’re saying what they seem to think you’re saying—and vice-versa. As to duck typing, it may work in programming (the debate rages on), but it is lacking when it comes to honest dialogue or logic—and, ironically enough, “moves like a duck, quacks like a duck,” pretty much describes Che Guevara’s approach to sending people to the paredón.
