The space shuttle was ultimately a vehicle for delivering crew and cargo to orbit.
This task is accomplished for less money by the falcon rockets.
Granted, If you put a ping pong table on the shuttle, its ping pong capabilities would be incomparable to the falcon rockets.

Space Shuttle:
Payload to GTO: ~3000 kg.
Average cost per flight: 1.5 billion (cost of shuttle program / number of launches)


Falcon 9 rocket:
Payload to GTO:~2000 kg
Average cost per flight: 50m (cost of expendable rocket)


Falcon 9 rocket with grasshopper gear:
Payload to GTO:~1000 kg (rough estimate)
Average cost per flight: ~200,000 (expected figure for fuel + incidentals)


You can do the math to figure out why this is a big deal.

I think that every engineer on planet earth should have -A mechanical pencil -A Protractor -An engineer's scale ( those three sided rulers) -Calipers - TI83/84 I'm not one of those old school flannel wearing engineers, I do most everything on a computer, but there is a lot of value in having a traditional drafting desk with tools like this, regardless of what type of engineering you do.
