The author isn't just talking about being hard or take a long time, as opposed to quick and easy. The scientist is suggesting that humans will never go; it seems to me that it's much too early into the history of spaceflight to make such a determination.
- jacquesm 7y agoNot really, there are some pretty hard limits on interstellar travel and humans don't seem particularly suited to the task either in lifespan, general durability and ability to deal with boredom. I like SF quite a bit but I'm well aware of what the 'F' stands for.
- Certhas 7y agoThat's an overly literal reading of the statements quoted. The context of the statement is "when it comes to treating our planet well". That is, at the timescales at which we are currently threatening the integrity of the ecosystem (~centuries) interstellar space travel is irrelevant.
