A bright future lies ahead for accelerator-based High-Energy
Physics. The HL-LHC prepares the FCC technology. The
Channeling conferences provide tools which can enhance the FCC
performance and already prepare for the future machines following
the FCC. Several different routes exist toward 10 TeV/100 TeV
and 1 PeV collisions, e.g. a linear path: ILC?CLIC?DWAC?
XRCMC, and a circular path: FCC-ee?FCC-hh?CCC. Crystals
are a key ingredient for the final stages of both routes, where they
are used either for bending or for acceleration. Eventually an outerspace
solar-system accelerator will be needed to reach the Planck
scale.
