So the odds of seeing the prompt in the wild aren’t too high unless you’re a Facebook user.
But as more apps show the prompt and it’ll become very common all you need is to agree once and you’ll then be more likely to opt in more than opt out, in my opinion.
I expect that 10k to 10x before the end of the year. Even then, 100k apps out of ~2M isn’t all that many, so it might take a long time for advertisers to regain the kind of access they had pre ATT.
ESPN, Hulu and Cruncyroll issue thepop up. Consider the reach of those 3 apps alone compared to the bottom 500k.
What does this mean?
"These sonograms are remarkably different from other sounds, as if birds “draw” with sound something that’s flying backwards in time."
The short of it is that most natural sounds product a root tone plus a varying amount of related tones above it. Our ears hear the root tone, and the other tones above it are what give the sound its uniqueness. That's why a guitar, a clarinet and 3 singers can produce the same note while sounding distinct.
Birds seem to produce a natural sound without a lot of the related tones above it. Their sound is, relatively speaking, much purer than most other natural sounds. That's very unique.
