Yes, but we had hopes that it would lead to more. And had lead to more, something only known to be false in hindsight, who knows where that would have ended us up? What if it upended the standard model instead of reinforcing it?
> Absolutely not.
What are we supposed to do then? As humans, I mean. No one knows why we're here, what the universe really is like. We have some pretty good models that we know are wrong and we don't know what wonders the theoretical implications of any successor models might bring. That said, do we really need to motivate fundamental research into the nature of reality with a promise of technology?
I'm not arguing for mindlessly building bigger accelerators, and I don't think anyone is - there has to exist a solid line of reasoning to warrant the effort. And we might find that there are smarter ways of getting there for less effort - great! But if there isn't, discrediting the venue of particle accelerators due to their high upfront cost as well as historical results would be a mistake. We can afford it, and we don't know the future.

But you are and they are. Just by the comments here its clear that even suggesting not to use untold billions on maybe pushing theoretical physics a little forward is meet with scorn. The value proposition either, in knowledge or technology, is just not well argued anymore besides hand waving.
No, I'm not and neither is anyone else. It's common sense that we should explore options that require less effort, just as one would in any project. I'm saying that we can't discredit huge particle accelerators due to, in the grandest scheme of things, a small economic cost and past results of a different experiment.

Sure, but it didn't. Which is knowledge that really should factor into the decision to build the next, bigger one.

Invest the money and effort elsewhere, for now. There are many other fields of scientific exploration that are very likely to yield greater return (in knowledge and utility) for less. You could fund a hundred smaller but still substantial intiatives instead of one big accelerator. And be virtually guaranteed to have an exciting breakthrough in a few of them.
And who knows, maybe a breakthrough in material science or high-voltage electrophysics will substantially reduce the costs for a bigger particle accelerator?

It was always factored in, and of course it would be in any next iteration.

I agree with this to a large extent. I'm just not against particle accelerators as a venue for scientific advancement and in the best of worlds we could do both.

Not this week, no. And if, next week (or next year or next decade) we resolve some of the most significant problems in modern physics, any expenditures in those fields were a waste?
You've repeatedly bashed particle physics based on your perception of a lack of progress vis-a-vis the costs, and claimed that other fields should be prioritized. Which fields? What would you hope to gain from those fields?
Is there no room for basic research that attempts to validate the bases (Standard Model, Quantum Field Theory, the marriage of the former with General Relativity, etc.) of modern physics? If not why not? Our models are definitely wrong, but they're measurably less wrong than previous models.
Should we not continue to hone/probe those models to find the cracks in the theories underpinning those models? If we don't, how will we solve these extant issues?
