How about the broad anecdotal consensus that Duolingo, a gamified language app, famously does not do much if anything to prepare people for conversational fluency.
"broad anecdotal consensus" very scientific. i don't disagree, but is it better than youtube? tiktok? instagram? (cocaine? meth? fentanyl?)
