Re: Not too surprised
You can never have too many telescopes. And you are also assuming the SKA will come online when they think it will. Does anyone trust time or cost estimates involving governmental funding?
Indeed, more is always better.
But to be fair, it could also be said that SKA is already online (in part) since various precursor facilities like ASKAP have been online since 2012. The nature of an massive array like SKA is that the "online" date is a bit artificial - the first time a Square-Kilometre worth of component parts start collecting data in unity on a single campaign. But it's really a process of building out (in some cases extant) facilities and then linking them.
