When will Wordle end?

We all know that the solution word is never repeated and that the word list doesn’t include plurals. At what point will they run out of possible words? Has anyone done the math on this?

Or, do you think they will restart and begin repeating words? Or otherwise pivot so the wordle can go on? I would hate to see it end as it’s become a staple of my daily routine. Thoughts on what wordle will look like when the inevitable happens?
