If we can detect the planets, we already have means of detecting large amounts of oxygen on a planet.
Those seem like 2 separate claims, and I don't see why one would imply the other.
Granted, we may only be able to detect a subset and even a small subset of life on planets with life, but with millions of planets, we are bound to find some
There are way more than millions of planets out there. There are probably way more than millions of planets with life on them. That doesn't mean planets with life are common, given the size of the universe. And it doesn't mean that we will be able to find any by 2045.
How common is life that produces oxygen in mass quantity?
It doesn't matter unless you have a way of showing that on a given planet, the oxygen was produced by life. OR if you just want to assume that any planet with a lot of oxygen must contain life.
And how good will our detection methodology be in the year 2045?
Probably a bit better than it is now. 2045 is only 31 years in the future.
