Thermonuclear ignition of an inertially confined deuterium-tritium mixture requires the creation of a "hot spot" with sufficiently high temperature, pressure and confinement parameter. In the standard ICF scheme such a hot spot is generated as a result of a high-velocity, directly- or indirectly-driven implosion. In this talk, I will first briefly review ignition requirements, outlining the conflicting requirements of high implosion velocity, implosion stability and implosion symmetry. I will then briefly discuss current achievements and present my personal view on the future of ICF research, and possible paths to ignition. Conventional indirect-drive and direct-drive schemes, as well as the alternative shock ignition scheme will be considered.
