2. RFID chips are expensive. bar codes will remain much cheaper even 10yrs in to the future. Metal carts interfere, and it will be difficult to differentiate that many rfid tags in one small space. If bar code scanners keep improving, rfid tags will remain a distant fantasy.

4. Predictions of internet congestion collapse have been predicted at least since the early 80s. It's no more true this time around. If anything, bandwidth just won't get cheaper as quickly as it has. Edge routers can throttle back speeds to prevent the backbone overloading. That's a slightly different model than we've used up until now, but technically fairly easy.

6. There are already articles about how pot dispensaries are becoming far less profitable as competition increases. In general, when items cease to be taboo, you can no longer charge a premium for them. Many industries suffer such a come-down.

7. We were supposed to be burning biodiesel from algae 30 years ago. Turns out it scales up very poorly, so barely made it out of the lab. Expect the same, here. In addition, directly producing electricity with PV solar panels, to charge an EV battery, is FAR more efficient.

10. Since dark matter may prove to be an observation or mathematical error, it's far from certain we'll ever "identify" it, any more than modern technology has allowed us to identify "the ether". A better radio telescope coming online is likely not going to be everything required, either.

I got an old pair of "distance glasses" from an uncle. They worked quite well, made distant objects less fuzzy and signage easier to read. However, they're decades old, so maybe laws changed since then, making them illegal to sell? It's a shame, if so, because such basic optics are quite useful for people without any eye conditions, and of course a cheaper option for those with just slightly weaker than normal eyesight.
A search for "nearsighted glasses" on eBay turns up 4,000 results, many allow you to select strength from -1 to 10. As low as $2/each, you could easily buy an assortment of strengths and, like any optician, see which works best for each eye, then order the proper pair, perhaps in a more desirable style.

I can walk into a dollar-store and get magnifying reading glasses in various powers. So what, exactly, does the law restrict?

I see that it's entirely legal in most states for an optician to DUPLICATE a pair of prescription glasses without a current prescription, so you can keep getting new ones indefinitely, without any further exam.

This is the kind of thing that gets people killed... Non-professionals offering bits of valid advice they've heard, mixed in with incorrect/bad advice, and missing some of the most important safety notes and disclaimers any medical professional would know to always include.

It's a tricky situation... Countries can't allow their citizens to go fight wars for others, with no official sanction, then flee back to the safety of their home country at will. It could drag her home country into a war they don't want. And consider what if an opposition soldier makes it to Copenhagen and murders her, but claims it as a valid wartime battle, not murder... Making the country a legitimate battlefield and individuals immune from criminal prosecution under the Geneva convention.

He's pushing his luck. The single shoe was 1. Worthless to the thief, and 2. Incriminating evidence, and apparently he saw a safe opportunity to return it rather than just ditch it in the trash.

This is much more dangerous than they admit. A burning gas stove without ventilation will release substantial carbon monoxide into your home. An unattended stove-top burner risks any stray bit of airborne hair or lint igniting and spreading to other flammable material in your home. Most pots and pans have plastic handles, which will release huge amounts of toxic smoke if they are left on a high temperature stove top without anything in them. Anything immediately adjacent to your very hot oven/stove risks igniting as well.

I highly recommend the Revenge of Shinobi soundtrack.

Ecco the Dolphin starts with funky, strange, otherworldly music, but only a few are good, the rest irritating.

Sonic1 Green Hill Zone on headphones recommended. They wanted to show off their stereo hardware, and did it well. Other levels/songs not so much, and they didn't bother doing real stereo sound again, even on Sonic sequels. Try it and tell me I'm wrong...
