There's just something sinister and "they only thought if they could, not if they should" like in that line about how we'll be able to achieve certain goals while sleeping. Like, that could mean good things (i.e. the mentioned help to mental health issues), but we all know that ultimately we can't even have sleeptime in this capitalist hellscape that is just for our relaxation, but to be the most efficient cog in the machine we must spend even our time of sleep to better ourselves to be our most productive selves when we are awake, to the profit of billionaires.
