That would be surprising, because the sun gets steadily (though slowly)
brighter with time. It started at 70 % of its total brightness.

I believe you mean 70% of *current* brightness.

ARGH! Of course. It will continue to get brighter and brighter. The end of life due to overheating is scheduled for one billion years in the future.
