Large Hadron Collider - largest most complex machine ever built. Thousands of scientists from around the world involved in the design, construction, and operation. Discovered the Higgs. Cost about $9 billion.

James Webb Space Telescope. Way behind schedule, too numerous to count technical problems. Dozens of a few dozen scientists involved during the project. Just launched, has not been tested in space or used for anything yet. Cost about $10 billion.

How many more important scientific discoveries could have been made if the JWST was cancelled early on the money used for other projects and spent by teams that could actually deliver projects on time and on budget?
