Quoting: "Trump has the intellect of a toddler."

Toddlers like it if you help them understand.

Not disputing your points, but JPEG2000 is used pretty extensively in the remote sensing world (think overhead satellite imagery from companies like Maxar [was Worldview]). These images are often huge (think GB+), benefit well from the compression and especially the inherent res levels J2K provides. It is a common compression format in NITF formatted imagery files. A niche area to be sure, but it is used.

Except time and willpower. However, the McDonald's analogy does hold up -- nobody is ever going to get rich flipping burgers at McDonald's, precisely because it requires so little skill to do that job, making McDonald's workers completely fungible. Since anyone can man a grill, no one is going to command a salary much more than what a high schooler will agree to do it for.

The economic problem with having an AI produce music for you is, you never get the opportunity to learn how to produce it for yourself. At the end of the day, you're paying them $200/month for the privilege of remaining unskilled, and you're competing against everyone else who knows how to enter "write a catchy song for me" into a prompt box. You can't make money that way, because the moment you do, the AI companies (who own all of the talent and all of the production machinery) can simply appropriate your income stream for themselves.

It's the difference playing Guitar Hero and taking guitar lessons -- both let you feel like you're a competent musician, but only the latter will ever get you a career as a musician.

Eh? This is incorrect. Perhaps most fictional murders are premeditated, because that makes for a more interesting mystery to solve, but in real life, the vast majority murders are impulsive, spontaneous acts that happen during arguments, fights, or emotional outbursts (often with the help of alcohol and/or readily available weapons).

You're right, they'll run the numbers and take whichever path maximizes their net profit -- but shuttering (or even heavily modifying) a facility that they've just invested $$$$ into is unlikely to be found to be their most profitable option. More likely they'll try to sell memory chips at a profit of +$.25 per chip in large volumes, because when you've got is a giant hammer, hammering lots of nails is what you can do best.

I wonder if anyone will start selling home systems capable of using cast-off data center RAM? It might be worthwhile if there's lots of that sort of RAM floating around for cheap.

Sure, a company could use an increase in productivity to allow their workers to work fewer hours while getting the same amount accomplished... but capitalism doesn't work that way. Instead, the company will use the increase in productivity to get more work done in the same amount of hours as before... or if they don't, their competitor will, and thereby obtain a competitive advantage over them.

This is especially true for salaried employees, where the cost of the employee to the company is the same regardless of how many hours the employee works, and it is therefore in the company's financial interest to maximize the return on its salary "investment" by getting as much output from the employee as possible in any given pay period.

I've got a co-worker like that; every email I get from him is just him copy-and-pasting text from his pet AI, and when I reply, he forwards my email on to his AI to read and generate the next reply for him.

Which raises the question... exactly what value is my co-worker providing there? Sooner or later management will notice that they are paying six figures of annual salary to what is essentially just a very slow meat-based email relay, and they'll lay him off and just have me communicate with the AI directly instead. There's a fine line between "all in" and "all redundant".

It all depends on one thing: Will your speech-driven AI agent reliably accomplish the tasks that you told it to do? If so, great, we've entered the glorious Star Trek future. OTOH if it screws up, even just 5% of the time, it'll be kicked to the curb, because a "timesaver" that you have to stand over and supervise to make sure it doesn't go wrong is no timesaver at all.
