Hi James, 2 things come to mind.
1) What are the tools we can use for metals in structural biology? Note, I am biased here… 2) Micro electron diffraction methods - ability to use on small crystals (which speaks to Tom’s point) and a potential bridge between cryo-EM and X-ray diffraction techniques? Awesome that you are asking for community engagement on this!

And if one wants to get into true costs- was it worth it to build the Large Hadron Collider to statistically prove that the Higgs boson exists? I'm guessing it was worth it to the folks that got their name on the paper...
