Although if there is some small possibility that X will be replaced in a couple of years shouldn't people be able to consider it?

Well, since it's hard to prove a negative, that then applies to basically everything. Look, people can "consider" whatever they want to. But I'll certainly complain about the normalization of making sloppy extraordinary claims on gut feeling. It's like some /r/wallstreetbets user trying to predict the future by the shapes & patterns of stock graphs. It's intellectually lazy and suggests lacking critical thinking.

Small possibility some natural disaster ends all life on earth in two years. Large possibility it will within decades

But hey more fun to pretend the chatbot will turn into Terminator

Well... whether the machines take over or just give us a common enemy, at this stage, the rise of Skynet seems to me like the highest likelihood path for global coordination.
