This depends considerably on the paper. Acidic paper, widely used because it's cheap, oxidizes in a few decades and degrades as you have seen. Because of this, acid-free paper has become increasingly popular. Your newer books are in fact likely to last much better than the ones dating from the 20th century.

I'm sure the three people who bought the vision pro will appreciate it.

Tinkering with a word guessing machine to see if you can make it smart is like breeding horses to be faster and faster expecting one to give birth to a locomotive. Word guessing machines are cool but they're never going to actually "understand" what they're talking about.

In one sense, taking on any engineering challenge you haven't done before always causes you to learn something new, so there's always progress. In the case of this particular program (Artemis) there's a lot of reason to be skeptical of what we're getting for the money. The original Apollo was done in a hurry with an all-hands-on-deck attitude, and amazing progress was made. When that program ended and the space shuttle program was created, there was less urgency, and politics dug its heels in. The only reason the shuttle program was allowed to happen was because different parts of the shuttle were manufactured across almost all 50 states. That made it inefficient, but also politically possible. The program itself wasn't as successful as originally hoped, and for reference if the cost of 1 kg to orbit on a (partially reusable) Falcon 9 today is $2700, then the space shuttle's cost of 1 kg to orbit was almost $55,000 in inflation-adjusted dollars. When the shuttle program was scrapped, funding to NASA for Artemis was only approved on the condition that NASA use all the same contractors and parts that the shuttle did. That's why you have two solid rocket boosters and shuttle engines powering the main stage, and a big orange foam insulated tank. And those 4 shuttle engines are thrown away with each launch. It's the least efficient way to do this, but it's politically possible because it keeps a bunch of money flowing out to almost all of the states. SpaceX is developing a new launch platform called Starship that's supposed to be fully re-usable, and the long term cost of 1 kg to orbit is going to be in the range of $150 (some estimates have it under $100). So the whole Artemis program is at risk of being obsolete as soon as Starship is proven to work. I would argue that it's already obsolete and a spending boondoggle, and I'm a space nerd who loves space exploration.

No it didn't. Nobody in "upper middle class" back in the 50's was "going on a vacation every year to a foreign country." Give me a break. And the general standard of living was much worse, particularly health care. Back in that "golden era" the life expectancy was significantly shorter, everyone smoked, and health care was basically anti-biotics, or nothing. They were still doing lobotomies. And houses were a lot smaller, poorly insulated, almost every kid shared a bedroom with a sibling, you had to wash your own dishes (gasp) because there were no dishwashers. Microwaves weren't a thing. Cribs came covered in lead paint. You were lucky if you had one television, and it was in black and white and got 2 channels. The one thing that an upper middle class family could do in the 50's was buy a new car every couple years, and that's because cars were a lot cheaper as a percentage of income, but they didn't have seat belts, airbags, power steering, and they needed constant maintenance and didn't last very long. Someone making minimum wage today lives better than royalty did hundreds of years ago. Get some common sense and learn about history.

..which doesn't support 486s, so the OP's statement that OS/2 still supports 486s is still not true.

Nonsequitur.

"More Americans have been entering upper middle class" is not inconsistent with "the economy has not improved over the past few years."

It's a stretch above 120th as well.

What are you smoking? The median household income in the US is roughly $84,000 a year. That would make $133k very clearly upper middle class. You know that there's more to the US than New York and Los Angeles, right?

"Entertainment purposes only" Note that they don't say *whose* entertainment.

"Support", not "in use". IBM sure as hell doesn't support OS/2 any more.

No, they only found the cow tools.

There was an initial large disruption as they dumped a huge number of packages into alternate delivery systems that weren't prepared for the sudden massive increase in load. Within a few weeks, it had settled down, and shipping times had improved enough that same-day and next-day shipping were once again available, albeit with shorter "order by" windows. The quality of the delivery experience has dropped significantly (in terms of failed/late deliveries) due to them relying exclusively on "Intelcom" (a gig delivery service) rather than Amazons own delivery system.

My understanding of how it works, at least for Montreal (which used to have multiple Amazon warehouses in the metro area), is that all orders are shipped from the Toronto area, a ~6 hour drive away. Amazon loads orders onto big Amazon trucks (semi trailers) and drives them to an Intelcom distribution centre in Montreal, and Intelcom handles the last-mile delivery. Intelcom doesn't do inter-city delivery, and Amazon doesn't have any infrastructure in Montreal (or Quebec more broadly).

As for why Amazon services Montreal's orders from Toronto (a ~6 hour drive away) instead of Ottawa (a ~2 hour drive away), my only guess is that Ottawa (1.5m metro pop) wasn't big enough absorb all of Montreal's (4.3m metro pop) demand, but Toronto (6.2m) was.

That ultimately won't matter, because the workers have already been laid off, and the courts can't order Amazon to reverse the decision. The best case scenario is that several years down the road, Amazon will have to make a one-time payout to the workers.
