Most things were using sulfur for photosynthesis and not CO2 and O2. Then tectonic events happened that caused O2 production to rise. Suddenly we had an oxidizing atmosphere that killed 80 percent of the diversity of life on earth while also changing the climate.

Great Filter - Wikipedia https://en.m.wikipedia.org/wiki/Great_Filter

... that's what the great filter is about. The reason this is good news is that it suggests that the great filter was whatever leap happened after that billion year stagnation, and not, say, immediately ahead of us.

It's also possible that there are multiple filters. So this might be A filter and not THE filter.
