So far 3 out of 5 items in the list have been called into question. Seems like an entire domain of knowledge might be a bit too broad to be summarized into listicles, even with the caveat that they are "rules of thumb".
Your sarcastic implication being that being good at managing car and space companies make him good at managing a social media company? Not only that, good enough to be better at it than his predecessor? Not only that, he's better at it within days of arriving?
Are people really expecting Twitter to survive The Musk? His rash actions almost feel like sabotage. I honestly expect Twitter to be dead or irrelevant in 2 years at most.
I am actually familiar with some of the research actually, but thank you for your condescendence.
I didn't mean to imply that the SAT or grades are not predictive of future performance, only that lower socio-economic statuses will correlate to lower SAT grades in the first place, ie your (a) proposal in the second source.
From this same source:
> The SAT-grade relationship is not an artifact of common influences of SES on both test scores and grades
To substantiate my initial comment, test scores are highly predictive yes, but as you just linked, SES is highly predictive of test scores (and this is only for people who get to the damn test). This is the tautological part. High incomes make people test well which lead to jobs with high incomes. But since this correlation is not 100% but merely very high, we can pat ourselves on the back and say hey it's accurate!
Articles that defend the accuracy of the system tend to implicitly defend its legitimacy, which I think is a much more important question than "is SAT indicative of future performance" when considering whether the SAT is useful.
Any study in this area that doesn't control for socio-economic factors is near useless, because it mainly predicts that children of successful (ie rich) people will likely grow up to be successful (ie rich). This is almost tautological.
There's still a dislike button, it just doesn't show the like to dislike ratio, so it's barely worth pressing. The outcry at the time seemed to indicate that this is explicitly to appease bigger media companies, who put out crap and don't care what anyone thinks (but do care about what people think other people think).
It depends what the point is. You wouldn't let a motorcycle participate in a horse race. I think there's a place for AI art and it's fine if "manual art" remains the same. The difference can be arbitrary at times, but art often is.
> Let me rent real servers, but expose it in a "serverless" "cloud-like" way, so I don't have to upgrade the OS and all that kind of stuff.
I think you're describing platform-as-a-service? It does exist, but it didn't eat cloud's lunch, rather the opposite I expect.
It's hard to sell a different service when most technical people in medium-big companies are at the mercy of non-technical people who just want things to be as normal as possible. I recently encountered this problem where even using Kubernetes wasn't enough, we had to use one of the big three, even though even sustained outages wouldn't be very harmful to our business model. What can I say, boss want cloud.
