It's hard to anticipate. If you'd asked me 20 years ago "maybe they'll invent a better apple" would not have crossed my mind, but Cosmic Crisp came out in 2019, and now I routinely eat apples which look and taste better than anything I previously imagined. My parents tell me they had the same experience with meal prep kits and Thai food.

True, but "a better apple" is unequivocally less impactful than "you no longer have to walk to the river any time you want to drink a glass of water."

I think it's easier to see if you think in 20 year increments. The difference between 1920 and 1940 is way larger than the difference between 2000 and 2020, and I don't think it's particularly close. Going from "antibiotics haven't been discovered" to "antibiotics become widely manufactured" in 1945 is a huge difference, just as one example.
