And here is the perfect example of why central-bank-crypto-currencies will fail.
I bet the f-c-book programmers thought they where helping out instagram by "making the feed better". However, what they were killing was the real experience and the usefulness of the platform.
In effect, f-c-book thought that they would just tweak things to make it a little better for advertisers, not realizing that the tweak basically destroyed the user experience.
And then f-c-book started working on emotional manipulation algorithms. This ended with a useless experience, that slowly made you crazy. You go there expecting one emotion and you get another. Its like someone Gaslighting you. It is what psychopaths do. Its crazy making, and f-c-book should be held accountable.
They love their money but I think what they love even more is the mind control aspect
