The James Webb telescope is an invention, designed from scratch, with many new breakthrough new technologies needed to make it work. There were 344 single points of failure that could have made it a total failure. Imagine, 344 individual things all had to go perfect while a million miles from Earth. And they did.

We will learn more than we can imagine, since we don't know what we don't yet know. Will any of it have a direct impact on day to day life, not likely. But the knowledge of how the universe works will unlock many new questions.

I suspect the next big mega thing that does affect everyone will be a small nuclear power plant that has almost no waste, and is totally safe, can't melt down Fukushima style and does not make bomb making materials. I hear Thorium - salt reactors are a possible answer.

I would say the smart phone and the internet were the last major world changing invention. Digital photography totally changed the photo industry. Commercial professional photography has been turned on it's head.
