Thirty years ago it would have been true to say "Solar is decades away from being viable as our primary energy source, whereas fission has been ready and able for decades." I really wish we'd gone with Nixon's 1970s proposal to make our entire grid carbon-neutral using fission, but given how the politics of that worked out, I'm also incredibly grateful that people kept working on photovoltaic technology anyway. We're building out solar pretty rapidly, and the technology has been advancing at an incredible rate, but we can work on multiple solutions simultaneously, and solar is a clear case study in why working on not-yet-viable technology is incredibly worthwhile pursuit.
