I'd say this is unpopular, specifically in tech circles (or maybe it isn't) - but at least from my personal experience, I sense a lot of pushback when I bring this up. You can come at this from a couple angles. One is technology. Interstellar travel, reverse aging (or anything functionally resembling immortality), teleportation, eradication of diseases, etc. all seem completely impractical or improbable to the point of impossible that on a macro level technology may hit a threshold. I think it's possible in the "personal convenience sense" (cellphones, driverless vehicles, enhanced nutrition and preventative care, etc.) technology may be *without limit* - although I wonder how much life will actually fundamentally change going forward.

As for social progress I tend to be more bullish, but I'm somewhat unconvinced, and feel natural or manmade catastrophes could threaten this.

If you want a kind of expanded view on this I recommend The Silence of Animals or John Gray's books in general. We don't see eye to eye on everything, but I agree with much of what he says about the myth of human progress.

I added a video explaining Gray’s concepts better than I can: https://youtu.be/OBhh_FepJaE
