Oh, that's right. I wasn't really placing the electron ion collider (EIC) under the energy frontier umbrella, because they're moving in a different direction. I'm actually sort of involved with them too, but from a distance. I'm pretty sure it will happen, it's just a question of which of two proposals will succeed (more of a political question to be honest).

My own interest isn't in colliders at all, but in building atomic probes like x-ray light sources and fast electron diffraction apparatus, but at a scale accessible to universities instead of large facilities.
