The post demonstrates how infeasible it is to travel to a location outside our solar system anytime in the next several generations.

What are some things you would like to see humanity do within our solar system within the next century? When do you think it is feasible to achieve that goal?

For in-system travel, we have to invest in space infrastructure, same as we did for the Oregon trail -> highways, the earliest sailing ships -> hydrofoil ships and aircraft carriers, and from covered wagons to cargo trains.

Skyhooks are a system of locomotion we could already do today, and save tons of expense on fuel and lift capacity, it's just staggeringly expensive to do. We would need to redesign our spacecraft and building the first skyhooks would be a joint nation-state endeavor.

Interesting high level overview on them here. https://youtu.be/dqwpQarrDwk

Pretty decent pre generation-ship technology.
