No, the joke wouldn’t have been as funny if it said “scammer” instead of “smart engineer”. Plus, I think it’s more a jab at engineers rather than anything. Because most would rather argue/explain the whole 10 vs 11 thing than just go "ok, sure, I can do that " and get paid.
Can confirm. Had a 16 year old work part time with me for a few weeks over the summer. Pretty cool kid, but yeah… Trump came up a couple times and both times he just repeated the bullshit that he’d heard from his parents. Sad shit.
