IllustrisTNG is the largest cosmological hydrodynamical simulation suite run to date, evolving volumes of up to (300 Mpc)^3 from cosmological initial conditions down to the present epoch with over 30 billion particles representing both dark matter and baryons. I will present a few key results on galaxy formation from these simulations and their predecessor Illustris. I will then focus on how the new generation of cosmological hydrodynamical simulations can revolutionize our understanding of the origin of galaxy morphologies. In particular, I will present a Lagrangian approach to thinking about galactic angular momentum content and touch on the puzzle behind the similarity between galaxy and dark matter halo spins.
