No, not yet, but those are long tail efforts. The technologies are the short term yield.
But discovering the electron was necessary for us to develop vacuum tubes. And developing quantum mechanics was necessary for developing transistors.
Think about the relative impact of the telegraph vs the vacuum tube.
When we do eventually find something to do with the W and Z bosons, it’s likely to look more like a transistor-level tech than an immediately practical tool like a lightbulb. But the second-order effects from whatever that new tech turns out to be, have the potential to be world-shattering.
High energy stuff only exists unstably for fractions of seconds. I find the idea that any of Standard Model physics, nevermind beyond standard model physics, could lead to a technological advance like the transistor extremely unconvincing.
Technological advance and scientific advance sometimes align. But there is no law that the former by necessity follows from the former. The expectation that they do is an extrapolation from a very brief period of human history.
This ended up as the theoretical bedrock upon which modern encryption algorithms are built, enabling trillions of dollars of economic activity (as well as spying and other nefarious or ethically questionable activities).
I noticed (as have others) that even the purest of pure fundamental research has this oddly persistent pattern of becoming applied to everyday problems sooner or later.
The x-ray telescope mirror design used for Chandra -- motived only by pure intellectual curiosity -- ended up being a key development stepping stone towards ASML's TWINSCAN tools that use focused x-rays for chip lithography. Arguably this is more important to the global economy now that even oil is!
Similarly, particle accelerators like CERN might be the next chip lithography beam sources. The technologies being developed for research physicists such as laser-driven "desktop" accelerators might be just the ticket to replace tin droplet x-ray light sources.
Who knows?
We certainly won't if we don't built these things for pure research first to find out!
It is hard to gauge this is in advance though. If you were sure what you were gonna find, it wouldn't be much of a discovery. Historically it has sometimes been decades before manufacturing and practical applications caught up to frontier research. For an extreme example, mankind knew of electricity in some form for 2400 years before doing anything practical with it. If all the people who prodded at it instead thought "man I can't imagine what this could be useful for" and found something else to do with their time, we'd live in a very different world.
Our civilization can afford to aim higher than incremental improvements on pixel density for screens on which to spectate people kicking a ball around. Personally I find frontier discoveries to also have much greater entertainment value than sports events and will happily fund them with a tiny fraction of my tax dollars.
Virtually all previous particle discoveries were predicted, and then we built devices to find them, eg. the Higgs was predicted in the 1960s. There is no such motivation here. There is no theoretical or significant practical benefit for the FCC, it's basically a jobs program.
There is better frontier research that could use those funds for much better payoffs. For instance, just sticking with particle physics, Wakefield accelerators would be orders of magnitude smaller and cheaper than the LHC while achieving the same energies. We've also never built a muon collider, and so that's largely unexplored territory.
We just don't need another radio frequency particle collider, we've reached the limits of what they can do within a reasonable research budget.
That's not true at all. To give just few examples.
Electron was not predicted but Thomson found it during first fundamental particle discovered came from cathode‐ray experiments, not from a prior microscopic theory of matte. Remember this was during thr 19th century.
Another one is the muon discovered in 1936 which was detected as "heavy electron" in cosmic rays. it did not fit any clear theoretical need in nuclear physics at the time, leading Rabi to quip “Who ordered that?”
Heck there are many more examples that I will bypass the comment limits if I tried to list them (resonances in particular will be very numerous).
You can of course move the goal target by narrowing what you mean by particle but this is exactly why physicists try to define what they talk about before making an argument.
> There is no such motivation here. There is no theoretical or significant practical benefit for the FCC, it's basically a jobs program.
Really? There is a huge volume of the feasibility study about the physics program of FCC. Are you claiming that it is false. Have you even read it?
No, there hasn't been any big "new physics" since the standard model in the 70s, everything has been refinement and specifics. You can't go to Walmart and buy something that couldn't exist unless we knew the precise mass of the top quark or the Higgs boson.
There have been a tremendous amount of developments and technologies that have come out of CERN with varying degrees of closeness to particle physics, but depending on who you're talking to, most of them don't count.

Ok, but Tim Berners-Lee was working at CERN when he created HTTP, HTML, etc.
The Internet through web browsers as you know it was created at CERN in order to enable scientific communication and collaboration.
It seems plausible to me that better understanding of the properties the subatomic particles might enable some previously unexploited technology (e.g. in quantum computing or sensing).
There are many ideas on how the universe works, right? Knowing which ideas are closer to the truth must be helpful to people who work on nano scale stuff, like chips so fine that quantum effect are considerable.
It must be somewhere between knowing if there's alien life or not AND knowing that atoms can be split at sub particles at will.
If you want to live in this world, you have to trade your time and provide value to others. You shouldn't get a free pass because, just because you convinced yourself and the government that you're smarter than everyone else.
"Decoupling science from the state" is just bullshit from "government icky, taxation is theft" morons.
No, governments should definitely fund scientific research. When it is public it is the only guarantee that it will benefit everyone. Scientific research done by private entities is kneecapped by their financial interests (and be very sure they will bury any advance that jeopardize their financial interests).
That's just how taxes work. Like capitalism and democracy, taxes suck, but nobody has come up with adequate substitutes that check all the necessary boxes.
Obviously still open to gaming and abuse, but it's not as if the current system isn't.
In case it wasn’t a rhetorical question, they’re in your interest because through the process of building them we improve our understanding of the world, develop new technologies which the industrial system wouldn’t have backed, educate the next generation of engineers and scientists, and inspire the kids that will form the second next generation.
Private research already exists and works well in some fields, mine included. But public research is just as important since it can afford higher risk and longer scope. You can’t begin to count the startups that were created as spin-offs of university research groups.
Scientific research is of societal interest, even if your particular interest differ. The best you can do is vote for parties that promise to shut down scientific research, or find another group of likeminded morons and form such a party with them.
If you disagree with the concept of taxes, well, sucks to be you. May your desires never come to fruition, because life would be hell.
Sorry, no. That's solid state physics on inter-atomic scales: tenths of nanometers, a handful of electronvolts. The LHC probes physics at the electroweak scale: hundreds of billions of electronvolts, billionths of nanometers. It has zero relevance to anything of practical use.
These accelerators are as large as they are to try and find mismatches between theory and experiment. And even then, we can explain virtually every experiment that the LHC has conducted. If we did find something unexpected with one of these colliders, it would only really apply to experiments made in the collider. Particle physics is irrelevant for everyday stuff since we already fully understand everything involved.
