The fact is we spend more money on K-12 education than any other country on earth, and results have been declining for 15 straight years. What, pray tell, makes you think spending even more money is going to get better results?

Are there backtesting results readily available for these models? What were their five-year-ahead predictions in 2000, 2005, 2010, or 2015? Were they too high? Too low?

We have world-leading healthcare and treatment options, if you can afford it. The problem is in how we pay for it and whether we would continue to lead in the development of new procedures and drugs if providers were forced to accept lower profits from a government payer.

I can't wait until AI is good enough to replace the senior executives. Then they will know what it is like to be a low-level employee who just got laid off.

For many years I was a Notepad++ user on Windows; it's a good editor. Then I started using Windows and Linux side-by-side and wanted one editor across platforms. Getting Notepad++ to run under Wine or somesuch was too difficult for me. Eventually, every good computer user wakes up, bites the bullet, and switches to Vim/vi. Runs everywhere, is actually easy to use after you do the tutorial, and has many advanced options for customization and other features as you get more comfortable using it.

" ... need to brand mushed-up trees with corporate nonsense despite this alleged digital age." Some of us prefer reading longer items on paper rather than on a monitor. It's easier on my eyes.

vi (vim) lets you edit files without programming or weird coding. Once you use it a bit, it becomes second nature. Or just stick to nano.

The deficit in FY2023 was $1.7 trillion and will be $2 trillion this year. Even if we rescind the Trump tax cuts and magically collect all $688 billion in uncollected tax cuts, we'd still be running a deficit.

Take a look at the defense industry. Elon is an amateur.

Disagree strongly as an occassional shareholder. For the most part Amazon only focuses on revenue growth, not profitability, especially in their retail division.

Why can't the blades be reconditioned, perhaps with a new coating of epoxy, then put back into use?

Amazon is the largest employer of PhD economists in the US. They have more than the Fed and more than the US government.

I guarantee the banks who lent money are going to take a bath on this. The company filed for bankruptcy, so the banks and lenders who financed this ship now own a partially completed boat with a very limited market of buyers who might want to take it, even at a substantial discount. They just want to recover whatever value they can from the boat. Banks lose money on loans all the time. That's why they charge interest rates on loans higher than government borrowing rates. The higher interest helps compensate for the fact that some loans won't be repaid.

Retail investors can and do participate outside of regular trading hours. I often buy shares early in the morning before much or at least some of the opening pop I expect actually occurs; and I will often have orders in after the close just in case a dumb investor comes in with a market order after hours and sells to me at a discount.

I've seen, first-hand, cases in which human input actually reduces forecast accuracy, at least with respect to economic forecasting models. I'm skeptical that human intervention is always appropriate when forecasting.
