Fe is only here to celebrate its farewell. The fad has peaked and the silliness exposed.
Flat earthers are returning to globe earth acceptance, in spades.
I would highly doubt that.
I think once genuine people actually start to question the global nonsense they simply get more interested in the alternatives.
Tough to say. FE seems to come in cycles...

Seems to be a precipitous drop-off, waning, since the peak in 2017.
That's hilarious. Do you think flat earthers are going around googling flat earth? This is like when wise tried to measure engagement by trending flat earth against nasa
Maybe, maybe not. But you missed the point. (Equally hilarious) The point is general interest among humans not just FErs. And it appears that general interest for FE peaked in 2017 and has welcomed a steady decline ever since.
One could argue that even though general interest has plummeted, it has leveled off to some degree above where it started, perhaps setting a new benchmark. Another cycle may come around when another rapper claims to be an FEr, interest will rise again and when it falls, interest may settle above where it is today. And so on.
Conversely, as pointed out earlier, as more and more that space travel becomes privatized, constant, global, and less reliant on government conspiracy theories, more eyewitness accounts, etc., the evidence may be that much more overwhelming for an attraction/interest to/in FE.
Or maybe it will take a meteor hurtling toward earth, an extinction event, to do so. Or global warming.
But in real terms, the problem for FE is that it's not just NASA!, NASA!, NASA! anymore.
But who knows in this wacky world of misinformation.
