In some districts the police can shoot you if they "feel" afraid.

There is little basis for any overt spoken threats of personal harm within a society, even when asserting self-defense. The right to self-defense should be presumed at all times and thus need not be asserted in speech as a type of overt threat. Overt threats, such as brandishing a firearm, are also subject to prosecution under a pertinent statute.

Insist on giving respect in public discourse rather than avoiding "hurtful" speech. Why? Because I cannot possibly anticipate every kind of way that another person might feel "hurt" by my words, even when my intent is to be very careful. Why? Because probably I do not know so much about the full lives of most individuals that I might speak to, whether in person (that is, directly) or remotely (that is, indirectly).

Capitalism is a greed-driven social system of resource consumption oriented toward building "wealth" (defined in terms of money) for individuals, so faster consumption produces correspondingly more privately owned wealth for cleverly managed enterprises, as opposed to conserving and/or improving resource sustenance that rewards everyone (including future persons) suitably.

Who's part of the solution, and who's part of the problem ..

It is mostly a waste of time to read the fantasies of so many others. Learning the sciences and mankind's own true history is a rich enough project.

We don't have knowledge or technology yet to permanently colonize anyplace that is extraterrestrial. An entire robust, sustainable environment suitable for humans would have to be transplanted. We must understand and fix the environment for human life on Earth first.

So that entails, to make a mission to an exoplanet that's more than making flyby measurements, a deconstructed (on Earth) and self-reconstructing exploration entity must be beamed to that exoplanet in many millions of pieces. Solar sail-transported pan-technospermia. So be it .. that is, if the road map for making something more robust definitely indicates that many further decades of development are required.

You don't seem to have really investigated the question. We're at the least talking about identifying the prerequisites for feasibility using today's level of knowledge and technology, some of which will be developed to become much more powerful in the next 100 years. Within that timeframe, for example, we can probably achieve economical fusion energy generation and large-scale mining of selected (mineral-rich) asteroids. On the other hand, I believe that today's claims about imminent AGIs are quite overblown.

A lot of human social engineering must take place to focus humanity's efforts toward extraterrestrial, much less interstellar, missions. When a critical mass of humanity comes to understand that those projects can "pay for themselves" with a "dividend" that enables building a much better Earth environment, I believe that humanity will have turned the corner toward perpetual terrestrial sustainability.
