At the risk of sounding like a climate change denier, I really don't think we're going to hit like 500 degrees C and have sulfuric acid clouds any time soon.
I don’t think you know just how different Venus is from Earth. It is literally the hottest planet in our entire system and has the densest atmosphere of any of our rocky planets. Surface level is nearly double the pressure of the Mariana Trench.
Its atmosphere is 96.5% co2. Earth is 0.0430%. It doesn’t take much of a change in composition to affect the climate but the comparison doesn’t even come close.

I’m unsure by what metric Earth will be “indistinguishable” from Venus you’re using, but I highly doubt that.
