Absolutely not. People may become less strict about either, perhaps for a short time or perhaps for centuries, but there will always need to be a core of conventional conformity at least on the most basic level. Because otherwise people will not understand each other. Everyday language use is a compromise between less effort and more clarity. If people can convey the same message with less effort, they will. If the clarity of the message suffers from their carelessness, people will put more effort into conveying it properly. So there’s definitely a rock bottom to hit, and I don’t think it’s very deep down from where we are now.
