I'm convinced there must be a prescribed US essay structure that mandates describing what you're going to discuss in the essay - it has been poorly translated into the style for youtube videos.
Yes, this is literally the case from grade school all the way into college level technical writing courses. The first paragraph, or first section depending on the length of the work, should essentially be a high level summary of the entire work. I remember in middle school we were also taught to write our paragraphs this way, that is, the first sentence should be a gestalt of the entire paragraph. The conclusion of each paragraph, and also the conclusory paragraph itself, is also supposed to have this behavior to some extent.
It took me quite a few years to realize how dry, boring, and repetitive this makes your writing, and I now choose to write as I talk. Might make for worse documentation, but it's far better for conversing with other people either in real time or in back-and-forths via email.
I have not had a joke backfire that caused me to buy a company at several times its value. I have not fired people, cutting off their healthcare, during a recession. I have not made my family hate me. I have not lied repeatedly and without punishment in public. I have not been sued by the SEC, Twitter, and countless other parties.
More towards the latter because Musk seems to have some pretty crazy and awesome ideas for the future but now we seem to be going a bit off the rails, especially in a time where economic uncertainty might lend to a more conservative approach. Up until now I can see the vertical integration of Musk's ventures, being able to share tech between Tesla/Spacex/Starlink/Boring Company/etc...but the behavior at Twitter is really in left field, almost like he is going crazy.
There are a lot of people I like to whom I would not hand over $50k+ for a nice product. For that kind of expenditure I want some certainty that the future outlook and mission of a company is on solid ground.
I spoke to a HFT software engineer who said how useful the limited market opening hours can be - memory leaks are a non-issue, just kill it at the end of the day.
