On one hand, perhaps theres an upper limit we're reaching to how far we can really get with what we've got. Sure, we could probably build a ton of nuclear rockets to go off in every different direction from Venus to Alpha Centauri, but we'd be destroying our own biosphere (or irrepairably damaging it), which is what ultimately sustains us, and we'd be thus dooming ourselves to extinction (which is what we're doing anyway on the path we're on).

On the other hand, something probably more disturbing than a slowdown in technological innovation is cultural backlash towards it. Social Media for instance has made many peoples lives worse, and has fueled conspiracy theories and skepticism/resentment of science across a broad spectrum, the worst recent instance was the response to COVID.

Its obvious to everyone at this point that technology evolved much slower and more disappointingly than what many people used to expect, but the culture that was once supportive of said innovation is turning more and more against it, especially as we live in the age where the honeymoon period of many technologies is far behind us in the past and we live with the very real drawbacks and consequences of its continued use.

We also have to consider that maybe more technology isnt going to dig us out of the hole we've put ourselves in and maybe we really do need to change the way we think instead of continuing down a disposable consumerist black hole.
