At work.
Okay. Some things off the top of my head.
1) It's BIG.
Find some picture comparisons of it and Hubble. In telescopy (New technical term I just made up
) 'Bigger' is pretty much always 'Better'. Hence we don't just see 'Farther' we get better details on things as well.
2) Just building it and successfully deploying it shows that, with this style of mirror arrangement, we can go BIGGER STILL!
The JamesWebb is the 747 size compared to Hubble's DC10. The 'Air Bus' version is yet to come. Remember, people didn't see the point of something like the 747 either, untill it changed the economics of air travel.
3) Because it mainly sees in the 'Infrared' a lot of places hidden by 'Interstellar soot' (Dust etc) will be effectively transparent to the J-Webb.
"Gee... what the fek is dimming 'Tabby's Star'? No idea because of all the crud. Good thing we can take a peak 'Through' that dust and maybe see what all the dimming is about thanks to the J-Webb."
The corollary to this is that the J-Webb can see 'Through' our Galaxy's disc full of stars and their collected amount of ejected crap and get even better images of things further away in our own neighborhood.
Like, possibly seeing the flickering hints of other fireflies out there in our Galaxy?
Just some things for shared rumination.
Cheers.

Can you tell me what Kepler, Hubble, ........ gave us other than knowledge for knowledge's sake (outside of the tech that may have been developed anyway on other missions)? That's my drift, shortsighted as it may be, there should be a cost-benefit ratio aspect.
