TIL that finding evidence of even microbial life on Mars could be very bad news for humanity. One of the most popular solutions to The Fermi Paradox is that there exists a "Great Filter" for life. Finding evidence of life elsewhere would mean the the filter is most likely still ahead of us.

I don't know where to start. Technology moves exponentially, always. I don't know what people you were reading in 1969 but suggesting you can say we have made no progress in space exploration is really ignorant. We have multiple rovers on other planets as we speak collecting data samples. We could have had a lunar colony already, but we decided it was better to have a space station. Personal robot slaves? I think Siri is pretty close - robot slaves for what else? We are about to deal with millions out of a job because they can be replaced cheaper with robots - thousands of jobs already have. Have you seen what a modern assembly line looks like? The tech for flying cars is here - it's logistics that stop us - autonomous cars will bridge that gap though. We work hundreds of hours less a year than in 1950, our infrastructure is being replaced at an astounding rate - that you see headlines just means you are not paying attention to actual progress. Trillions in debt? Yes - that's called inflation - our debt to GDP is not even close to the highest it's ever been. Billions in poverty? It's called two people having eight kids...not sure what you expected here. Rise in medieval ideology? No, they are just louder and get more ad revenue for TV.

Can you give cite a tech invented even just 10 years ago that has not seen exponential growth?

But to assume that we will enjoy uninterrupted exponential growth over the next few million years

Who the hell said this? I am talking about a fictional civilization that already is capable of harnessing the power of an entire galaxy. You are arguing that despite the power to manipulate the output of stars, they would colonize at a rate of one galaxy a year for eternity. I am arguing that they would not - they would colonize exponentially...and we would likely have seen evidence of them if they existed in this capacity only a few million years ago.
