No more unrealistic than the massive valuations on the stock market of social media corporations that can supposedly back it up somehow (with AI! or something… VR maybe?) despite the fact that fundamentally these social media places are becoming crowded rooms of bots pretending to be humans all trying to manipulate each other.

My point is, we will figure out how to sustainably scale before corporations do because the metabolism of massive tech companies precludes them from giving a shit about that.

At this point, inefficiency is a virtue for these corporations as it degrades the environment around them making future alternatives unlikely to be able to gain a hold in such a broken context.
