Great article, but have to disagree on one!
'Life on the Sun like our own' has of course been gleefully debunked.
But we can't write off life-like process forming in high-energy states that may use a completely different set of processes or even come from a different era. They may operate at absurd energy states, go through generations before we know it, and they'd never escape that gravity well with any sort of mass . . . but we always have to be careful when we think we 'know' things. We are just teensey little humans with very limited views.
Authors like Gregory Benford, Charles Scheffield, and Stephen Baxter have dabbled a little there, still from our limited viewpoint but with their lovely brains and have touched on some possibly plausible mechanisms.
That's something we need to keep in mind if we ever consider MESSING with the Sun generations hence.
