I would assert that the "here are the current flaws" side is still necessary in the overall conversation, since they provide the necessary feedback that allows technology to improve. Similar to political debates influencing the Overton window of a population, I see the "future promise" vs "current flaws" as a human algorithm realizing itself. The debate never ends, but the "mean" value keeps moving as technology progresses. As a "future promise" person myself I used to be annoyed by the "current flaws" side as well until I started seeing things through this lens.
