user23662: Since the Buddha said everything is impermanent (anicca) 'yan kinci samudaya dhammam sabban tam nirodha dhammam' and ignorance (avijja) is something, won't it be the case that ignorance (avijja) will cease for everyone (ordinary folk (puthujanas) and those-in-training (sekhas) alike) eventually?
The Buddha did say that ignorance (avijja) is impermanent (anicca) actually.

user471: This is a great question!
Ignorance (avijja) is impermanent (anicca). Everything that arises must cease.
So, will we all become liberated? Will we all become enlightened?
But, we must also remember sabbe dhamma anatta - all phenomena is not self.
So, ignorance will cease. Not necessarily for you or for me specifically, but it will cease eventually. And it will also arise again - again not for you or for me specifically.
The same goes for suffering (dukkha).

user254: The Buddha said that all conditioned things -- all sankharas -- are impermanent.
So to answer (or gain insight into or from) the question, you may want to ask, what is the condition for avijja and what is the condition for its ceasing.
