Ab initio calculations of atomic nuclei aim at describing their structure and reaction properties starting solely from the basic interactions between nucleons. In the past decade, thanks to developments in many-body theory and in the modelling of nuclear forces, such approaches have steadily progressed and are now able to reach several tens of isotopes up to mass A~100. The long-term goal is to eventually extend such calculations to the whole nuclear chart, i.e. to several thousands of nuclei up to mass A~300. In this context, one of the main challenges consists in devising methods that can tackle strongly-correlated systems and at the same time scale gently with mass number, in order to limit the computational cost of the simulations. Current efforts towards this objective will be presented, together with the discussion on recent examples of ab initio calculations. Future perspectives in the field will be addressed.
