Agreed.
(Granted, I don't actually think the "Bulma is stupid" argument is
that bad. Someone pointed out that it's implausible that she can create a time machine & achieve all sorts of insane technological feats, yet doesn't fully understand the size of the universe. On its face, this is fair, but I think this point is undermined by the fact that Future Bulma was capable of creating a highly advanced time machine, yet wasn't capable of building a space-ship to collect the Dragon Balls from New Namek. To be fair though, these are different versions of Bulma, and one could argue that DBS Bulma is simply more capable than Future Bulma.)
Also, were there any more recent threads on it? I couldn't find anything newer than
this one, and there were more people supporting the Infinite universe than disagreeing on it.
