How is infinite growth physically impossible? Human demand for goods, services, experiences, etc is insatiable. And production will meet demand.

just like the sun burns up all its hydrogen stores eventually, the earth will eventually give up the last of its natural resources. Sooner, rather than later if we keep up at this pace. Unlike the suns nuclear process, though, our use of resources is unnaturally accelerated.

That won't happen in the next several centuries. We will have accessed the resources of the solar system by then.

No, we won't, not the way we're going now. We don't have the technology to extract offworld resources, and we're not doing anything right now to change that, except for some hot air from a few places.

Most likely, our environment is going to become uninhabitable within 50-100 years, causing our population and societies to collapse, and while a few of us may persist in some domed cities for a bit, instead of building more technology to move offworld, we'll have a big religious war and then go extinct. Hopefully, some other species will eventually evolve to become intelligent and do much better than we did.

Even if your every desire was fulfilled for 24 hours a day, you can't create a 25th hour.

I desire a time machine.

Checkmate.

Some days have 25 hours.
