experimental physics - What technology can result from such expensive experiment as undertaken in CERN?

I wonder what technology can be obtained from such very expensive experiments/institutes as e.g. undertaken in CERN?

I understand that e.g. the discovery of the Higgs Boson confirms our understanding matter. However, what can result form this effort? Are there examples in history where such experiments directly or indirectly lead to corresponding(!) important new technology? Or is the progress that comes from developing and building such machines greater than those from the actual experimental results?

Answer

The truth is we don't know. But when you think about it, how can we know? If we knew what technology would eventually come out of experiments like this, why would we not build that technology now?

Large expensive machines like the CERN supercollider help us to further understand the laws of nature. And through understanding these laws, new technologies arise. But we, the physicists, have absolutely no idea what wonderful technologies might result tomorrow because we invested so heavily in science today.

It's purported in 1850 after Faraday developed the electric generator, the British minister of finance asked him what practical value there was to electricity. Faraday could not have known that electricity would one day form the backbone of all modern society (but that didn't stop him from making a snarky remark). It's hard to predict the future; we labour in science in the hopes that what we do will prove useful for some new and amazing technologies. But we don't know what technologies will result from our expensive laboratories any more than Faraday knew that electricity would allow you to make a computer.
