Currently, cosmological simulations such as IllustrisTNG or Eagle are run by solving (magneto)hydrodynamical equations numerically. By the end of 2027 will at least one of the leading projects of the time (by number of citations and based on my judgment) rely critically on machine learning technology such as graph neural networks?

For this to resolve YES the main hydro/n-body simulation engine must become AI accelerated, not just the subgrid physics.
