Why is there such a long time between seasons of modern, streamed TV shows on Netflix and similar platforms?

Back in the day your favourite shows ended in may or June and your wait for the next season premiere was 4-5 months.

There’s 3 years between season 4 and 5 of Stranger Things. Over Four years between season 2 and 3 of Euphoria. The next season of The Last of Us won’t be out until at least 2027.

Why can’t these, and countless other shows, be made quicker?
