Pushing forward the energy frontier with a larger collider is the only surefire way we have to understand the structure of matter at smaller distances. From the fantastic experimental work of the LHC we now understand the visible sector down to <~10-19 meters. The FCC would allow us to push reductionism to even smaller distances, below 10-20 m. The only other option is to give up on the program of understanding the short-distance structure of the universe.

Did the prize task seem a bit off? It cut Karen's bit immediately, and then Jeremy's feedback didn't really make sense. I wonder if he was referencing some argument they ended up cutting.

I saw a bunch of live GM's GM-SBs listed on Guy's website and they looked like a lot of fun. Any idea if Guy was recording these? Would be lovely to watch without having to fly to Australia.

They're measuring the W mass empirically by looking at the kinematics of its decay products, so that inference doesn't require assuming a value for the vev or the coupling or whatever.

Sure, that's true---the number of degrees of freedom in the early universe controls the expansion rate, for a start.
We've only definitively answered the question of how many there are in the past ~10 years, by measuring the rate of Higgs boson production at the LHC. There are exactly three generations.

Hahaha thank you for pinging me! I guess if people are somehow still being led to this thread I should provide some update. TL;DR: I'm still in physics! But it's been difficult and YMMV.
Senior year I applied to graduate schools whilst taking too many classes, which was exacting. But it worked and the next year I went off to a top physics department. Grad school was difficult and stressful and overall left my mental health in a rather worse condition than it had been, but I managed to be productive and do some interesting things. Postdoc applications were again stressful, but I got an offer from a great group where I now am. And now I've struggled as a postdoc in the middle of a pandemic and I'm worried I haven't gotten much done. But I think I've had some interesting ideas that will come to fruition before too long, hopefully.
Anyway, I'm quite glad to say all these years I've been paid to think about physics. And that it's still possible that I can continue to make a living doing so going forward. I don't at all regret not having pursued more profitable options that would not have allowed me to think about physics. But it's also true that other jobs might have consumed less of my life, or other paths might have been less stressful.
Take this with a grain of salt, though, as I'm only now a postdoc. Perhaps I'll have to revise this comment in 7-8 years. ;-)

I continue to enjoy this, but my gosh can that laugh track be off-putting sometimes.

Rabbits aren't mindless automata. They're mammals just like you and me, and in fact you and that rabbit have a shared ancestor who lived less than 100 million years ago. I can't immediately find anything about 'how far they can think ahead', but they have social structure and build nests and find food, etc. Clearly they 'know what's going on', so to speak.
