Thanks. Indeed, time travel would be another extreme possibility, but you're talking about the substantive issue of whether the coverup is real. I'm addressing here the adjacent issue of what the coverup would imply.
I don't have expertise on the empirical question of what the far future will be like. I talk about transhumanism as the culmination of a civilized revolt against nature's wildness. But this is a conceptual, sci-fi possibility. How could I know whether it's likely to occur? There are lots of ways our species could evolve. I can speculate like anyone else, and I enjoy science fiction but I wouldn't have much confidence in a timeline leading up to the distant future.
Indeed, though, time travel from a transhuman future might be easier to imagine than the simulation hypothesis (alien intervention from a higher dimension). I suppose the simulation hypothesis would be more apocalyptic, though.
Are you familiar with the All Tomorrows timeline? It's pretty wild as an exploration of the horror of deep time:
