There are a lot of memes in recent years that literally don't mean anything. They are just statements that young people repeat soley because not repeating it means you're left out. 6-7 is one such meme.
It's not really any different from other trends, it's just that usually you can at least see why a trend caught on to begin with. Thus your confusion.
I'm in software. The company gives us access and broadly states they'd like people to find uses for it, but no mandates. People on my team occasionally find uses for it, but we understand what it is, what it can do, and what it would need to be able to do for it to be useful. And usually it's not.
If I thought anyone sent me an email written with AI, I would ask them politely but firmly to never waste my time like that again. I find using AI for writing email to be highly disrespectful. If I worked at a company making a habit out of that, I would leave.
Then they came for the drag queens, and I stood with them, because I know how the rest of the poem goes.
So, the Republican shift toward the far right was already in full swing by the 2000s. You'd need to go back to at least Reagan to head that off. Trickle down economics, Two Santas, etc. was already decades in the making. My dad had already been fully brainwashed by talk radio in the 90s.
But on the flip side, the Democratic establishment has made it painfully clear even to this day that their only priority has always been to maintain the status quo for the privileged NIMBY class. The Republican party didn't need to do anything to keep unaffordability rising, they all want to maintain the housing market bubble to protect the wealth of boomers.
Yeah, a focus on altruism, but make investments to be more effective at it. Hey, you could even get ahead of the game and start a crypto exchange!
Idk but an AI will have written it, and 99.9% of its views will be from bots.
Yeah, I knew about the song, but afaik it didn't "catch on" until "6-7 kid" did a thing. And now everyone just makes the reference any time they think of it, because they saw someone else make the reference, not because it's ever applicable.
I have to assume there is a field of study of memetics that draws a distinction between "merely a reference" and "applicable". Ex. When a person refers to the "this is fine" meme, it's because they're invoking a sentiment that is applicable to the discussion, which is socially useful because you can build off of a common understanding instead of needing to lay the groundwork first to be on the same page (insert captain america meme). But when people say 6-7, they really are just saying "this is a thing we both are aware of".
OP is basically asking "when is this meme applicable?" And the answer is, it never is.
