The position criticized in the tweet is that people don’t care about workers in poverty now because they imagine a future in which that worker has a better job, and they forget about the person then put in poverty working the first position. The point is that the imagined future does nothing to help the real person suffering now nor reduce overall suffering even if it were realized.

Your imagined future of automated post scarcity has the reduced overall suffering part but it does nothing for people still waiting for their shitty jobs to be automated. You also don’t suggest any way of enforcing an equitable distribution of this automatic production rather than allowing it to be owned by the same people who own everything now, who have chosen to structure the current economy to keep so many in poverty.
