Not sure how any serious engineer or scientist works at NASA these days.
I work at a NASA research lab, and find it a rewarding way to spend my time... I've seen exoplanets through the eyes of space telescopes. I've invented AI algorithms and then flown them on smart satellites. My code has run on a rover traversing the surface of Mars. I agree that commercial enterprise has a role to play - but for all its imperfections, NASA is still a pretty remarkable institution at this particular moment in human history.
