The changes of the past 100 years alone are so sweeping, it is impossible to accurately know what to expect in the next 100 years. Probably even greater change, which I hope we will be here to like.

However, even with white LED lights, and advertising messages on rotating Radio Shack airplane propellers, I expect some things to remain the same, such as the kerosene lantern, which will be lighted by a piezoelectric butane "match".

It's true, some plums (?or prunes) won't even grow on the tree, if they have not been pollinated. (Just was reminded of this on a gardening show on the radio.)

We could always mass-produce pollen by a DNA cloning process, I guess, and get more inferior product, much like the cardboard corn flakes.

-Who will invent the way to include diversity in the artificial pollen?
