You're totally right about all this, in my opinion.this is almost out of date to be cancelled now, i feel like its usage crashed with the crypto bubble bursting, but i really hated "gm" as soon as i saw it.
it was the essential utterance of the crypto-evangelist/brainwashed, shorthand for "good morning". what i thought was interesting is that it seems fairly harmless - how can you get annoyed at upbeat people saying good morning to each other on discord or twitter everyday? doesn't this seem like a nice community? but it's actually the social equivalent to the buy-in for the pump and dump scheme. keep up the relentless facade of optimism about the utilities of the pyramid scheme product so that you can keep pulling people onto the lower rungs.
there are whole channels in some of the crypto project discord servers that i'm still in that are dedicated to people saying gm to each other. you even get a bot recording your gms and giving you points for gm-streaks.
wagmi - we're all gna make it - that was another one. i think people call it toxic positivity
And toxic positivity is the right term here. All the worse when the bulk of this ostensible positivity is propped up by bot armies for marketing campaigns.
