Large telescopes have been objects of interest and fascination for many years. Today it seems that very large optical systems for ground and space are entering into a new era of development. For ground-based astronomy alone, one can identify a need for up to twenty 7.5-meter-diameter primary mirrors, some of which will go into telescope arrays of such giant mirrors. Possible space-based systems have even greater potential size and resolution capabilities. This talk will focus on the present and the required technology for such telescopes, and will try to sort out the reality and the mere possibilities in the design and fabrication of such next-generation monsters. As no surprise, the work at the University of Arizona will be emphasized.
