\section{\ref{sec:conclusion} Conclusion}  \label{sec:conclusion}  The discovery of the H(126) particle at the LHC has focused studies for the next machine needed for high-energy physics. While brand-new ideas are emerging for future Higgs factories, the prospects for the next decays look decade  already look  quite promising: the HL-LHC is indeedalready  an impressive Higgs factory, with great potential for Higgs boson coupling measurements to a few per-cent accuracy. The run at 13-14 TeV may discover something else, unfortunately likely to be beyond the ILC reach. Beyond the HL-LHC, it is now generally accepted that it is important to choose the right machine, as not to mortgage the future of the discipline with a suboptimal choice (given the cost of these machines). To cut a long story short, the right machine must bring orders of magnitude with respect to what can be achieved at LHC, both in precision measurements and in discovery potential. It has been shown in this article that the ILC project has neither of these capabilities, with both too small a luminosity and too small a centre-of-mass energy.
