Seriously, does bitcoin has fixed life in internet and crypto world?

Maybe I'll ask questions which were already answered but I am really interested in it.
We know bitcoin's supply is fixed, 21 million. Mining will stop after that. So who will confirm transactions? I guess miners will be forced away from the block rewards they receive for their work. So I think transaction size must be 100x more to keep low fees.
But I think there will be a need of redesigning whole bitcoin's abilities, how it works and etc. Currently it's great but will it be so great in future without changes?

If that is a technical question I don't know the answer, but from a practical point of view, the last bitcoin is supposed to be mined sometime in 2140, if bitcoin even exists at that time. Since it is impossible to predict what the world be like by then, I think it doesn't make much sense to speculate about it now.
