The concept of a Square Kilometre Array was developed to ensure that progress
in Radio Astronomy in the early 21st Century continued at the same impressive
pace as was achieved during the first 50 years. The SKA telescope is designed
to pave that road to greater and greater sensitivity. So what technical
challenges does the project face and what key innovations will drive the
success of the SKA? What will the next Radio Astronomy mega-science project
look like? In this article the author discusses the likely avenues of progress
in the coming decades and comments on the status of radio astronomy in 2049 -
the author's 70th (and presumably her retirement) year.Comment: Conference Proceedings PoS(RTS2012), 8 pages, 1 figur
