The ESO Extremely Large Telescope project is in the final stages of AIV. The bulk of the telescope and dome are erected on site and almost half the primary mirror segments are already in Chile. The rest of the optics are well advanced as are the wavefront sensing capabilities. The talk will present the current status of the hardware and software systems and discuss the issues arising from thinking about, designing, and building the telescope.
