I feel like the only real answer is "we just don't know". But in an attempt to actually answer this, I think the breaking point are different for different groups of people.
If you are struggling to pay the bills, you probably could care less about software's 'decline', you're just trying to survive. Maybe if something catastrophic happened it would be enough to put you at that limit, but software could stand to get much worse before then.
If you are forced to interact with technology a lot everyday, then what might be a paper cut for someone every once in a while, could be literally hundreds a day for you. In that case you are probably very near or at that threshold already.
As a society, I don't think we would see cracks until we start to see multiple community scale disasters related to poor software, or small disasters in highly visible areas like healthcare, planes, etc.
