That's not optimism, that's a dystopia - a world where most humans simply exist, with no meaning. Doing remote work on the road seems pointless as there's no work to be done anymore (also rest of the world has trains already to allow that).
This is something only comfortable first-world inhabitants tell themselves; as if the coffee they drink that some poor plantation worker toiled away in the heat for while some fat cat extracted the surplus value of their labour was part of a benevolent system designed to bring "meaning" to the less fortunate.
ah yes, compared to the current day where most humans are full of meaning at their bullshit jobs
