ILC250 Cost Update - 2024
The International Linear Collider was conceived as a global project for an energy-frontier electron-positron collider.It employs superconducting RF and nano-beam technologies with a center-of-mass energy of 500 GeV. Its cost was estimated in 2013, based on the Technical Design Report published in 2013.Japan's high-energy community proposed to host the ILC in Japan as a Higgs boson factory at 250 GeV in its first phase, and a revised cost estimate was conducted in 2017 to host it in Japan. Howev…

Quite extensive writeup on the whole W/X situation, the title suggesting too political of a discussion - I do recommend reading through it, neglecting stances, and just seeing where the projects stand.
To be clear, I do not endorse or judge anything here. It helps getting an overview. In the end, there are too many aspects, and deciding for either solution requires you to consider your personal preferences and priorities.
