I've added claims from a wide gamut of people (some just random Internet users), but here are a few:
2021-10-02 (did not come true): "I would not be surprised if Apple completely closes off the Mac ARM64 platform for “security” in the next few years. The option to boot third-party OSes seems like a short-term gimme to keep the pitchforks and torches at bay." -- https://news.ycombinator.com/item?id=28731406
2022-04-04 (we will soon see): "Unless we see big structural changes in the Democratic party's coalition, then the modal outcome for 2024 is Donald Trump winning a filibuster-proof trifecta with a minority of the vote." -- https://twitter.com/davidshor/status/1511028728381734912
2022-11-18 (did not come true): "I do not think Twitter will die, but it will go down in the next few days due to the World Cup and its overwhelming traffic. When it does, Musk will dedicate himself to bringing it back up, and boldly claim that his mission is to “keep Twitter standing.” In the background, he will realise that nobody wants to work for him, and that there is no path that involves him running (or even keeping) this website that resembles any kind of success." -- https://www.wheresyoured.at/the-fraudulent-king/
You are seeing the first two as "concluded"? Apple is known for playing long games, especially now that they need to be careful due to threats of regulation, and studies about long COVID take a long time - we really don't have enough research yet to be sure and we're barely 2 years out of the pandemic.
I'm holding my breath on both of those but I'm curious why you think otherwise.
For the first, the prediction was "in the next few years." If we take "a few" as three, that would bring us to 2024-10-02, which was earlier this month. It could still happen someday, but didn't in the time frame of this prediction.
For the second, "sooner than anyone can imagine" is admittedly not a specific time frame, but we're 2.5 years later and I haven't heard any news about long COVID lately, certainly nothing calling it a crisis. But this also could certainly change in the future.
The reason you don't hear any news about long covid is that it affects peoples brains, hearts, immunity, microbiome, organs, and employability. The hospitals do not attribute the rise of problems in these areas to long covid, so there is no news about long covid as the ultimate source of increases in childhood diabetes, the rise of autoimmune diseases, middle age heart attacks, a higher background death rate, decline in lifespan, availability of workers, etc. These are all reported as isolated mysterious facts that nobody understands. But just prior to the rises was a huge pandemic from a disease that causes long covid with many research reports of very long lasting damage to multiple systems in the body; maybe the cause is not so mysterious? Swiss Re the insurance company is certainly paying attention.
And the pandemic is not over, more people are getting long covid right now and it's not just the old people. The main fear is that this is a slow moving crisis where 5% of all people lose _some_ capability every year, including the capability of fighting off other infections, and also including those who are reinfected. It doesn't take long for that to have widespread effects and indeed effects are showing up and there are already economic consequences. The reason researchers were saying "sooner than anyone can imagine" is that this is an exponential effect and now that the CDC is no longer collecting data (and much of the world followed suite) it is difficult to predict with precision. However, like all exponential effects it will at some point start the steep part of the upward climb.
