I mean, things rather fall down in the extreme case. If my brain is spared the ravages of time, we could say I'm guaranteed to continue to close the gap as time passes, but I don't think this is a helpful way to look at things. In reality, there are limits to what you can do with a trained ape. An usually long-lived ape doesn't much help you. I suspect the same applies here.
