Comment Not new, but getting worse (Score 1) 55

I remember a fair number of people in the '80s getting fooled by Eliza, a collection of heuristics designed to create the illusion that the computer understood what was being types and formulating reasoned responses. Of course, it was doing no such thing.

Modern chatbots do a much better job of it. 'Good' enough that susceptible adults sometimes go over the edge into a full mental health crisis after a month or so interacting with them.

The constant affirmation and un-wavering support makes the chatbots the ultimate yes-man. We have all seen what happens when celebrities and people in power become drunk on their own yes-men.

It's worse than internet echo-chambers. At least those don't tend to let the conversation get that personal and specific. Chatbots will get as personal as you wnt and they are designed to never break engagement (how will the company keep gathering underpants if the chatbot keeps saying no?).

And all of that with adults. Now imagine turning all of that on a young teen that hasn't had time to mature enough to know better. YIPE!

You're missing that both a bleed air system AND poor maintenance are required for this problem to manifest.

Presumably the other planes with a bleed air system are getting better maintenance, so haven't been a problem. No idea how the 787's maintenance is, but since it doesn't have a bleed air system, the problem of dangerously contaminated cabin air hasn't manifested.

More specifically, this happens when engine oil or hydraulic fluid leak into the engine while bleed air is being drawn.

Even if it seems to save some money (probably not THAT much in the end), it'll still cost them.

In 10 years, the Vibe coding kids will be middle-aged vibe coders, but the entry level engineers would have been senior level engineers. Eventually, once you were ready to retire or move to management, one or more of them would have been the new you.

Instead, now when you retire, they'll be swimming in a sea of middle aged vibe coders and nobody left will have a clue how to fix the horrors that they produce. They won't be able to hire a new you from outside because the other employers followed the same strategy. They will be no replacements available.

They might be able to eek out a few more years by paying someone a king's ransom to come out of retirement for a couple years, but for obvious reasons, that won't last forever either, even if they can afford it.

Comment Re: Legal/illegal bikes (Score 1) 146

Class 1 and 2 e-bikes limit assist to 20 mph, not 15. You can ride them faster than that, but you have to provide the power. 20 mph is well above what most recreational cyclists can maintain on a flat course, so if these classes arenâ(TM)t fast enough to be safe, neither is a regular bike. The performance is well within what is possible for a fit cyclist for short times , so their performance envelope is suitable for sharing bike and mixed use infrastructure like rail trails.

Class 3 bikes can assist riders to 28 mph. This is elite rider territory. There is no regulatory requirement ti equip the bike to handle those speeds safely, eg hydraulic brakes with adequate size rotors. E-bikes in this class are far more likely to pose injury risks to others. I think it makes a lot of sense to treat them as mopeds, requiring a drivers license for example.

Would treating them as mopeds be so bad?

What weâ(TM)re looking at is exactly what happened when gasoline cars started to become popular and created problems with deaths, injuries, and property damage. The answer to managing those problems and providing accountability was to make the vehicles display registration plates, require licensing of drivers, and enforcing minimum safety standards on cars. Iâ(TM)m not necessarily suggesting all these things should be done to e-bikes, but I donâ(TM)t see why they shouldnâ(TM)t be on the table.

I am a lifelong cyclist , over fifty years now, and in general I welcome e-bikes getting more people into light two wheel vehicles. But I see serious danger to both e-bike riders and the people around them. There are regulatory classes which limit the performance envelope of the vehicle, but class 3, allowing assist up to 28 mph, is far too powerful for a novice cyclist. Only the most athletic cyclists, like professional tour racers, can sustain speeds like that, but they have advanced bike handling skills and theyâ(TM)re doing it on bikes that weigh 1/5 of what complete novice novice e-bike riders are on. Plus the pros are on the best bikes money can buy. If you pay $1500 for an e-bike, youâ(TM)re getting about $1200 of battery and motor bolted onto $300 of bike.

Whatâ(TM)s worse, many e-bikes which have e-bike class stickers can be configured to ignore class performance restrictions, and you can have someone with no bike handling skills riding what in effect is an electric motorcycle with terrible brakes.

E-bike classification notwithstanding, thereâ(TM)s a continuum from electrified bicycles with performance roughly what is achievable by a casi recreational rider on one end, running all the way up to electric motorcycles. If there were only such a thing as a class 1 e-bike thereâ(TM)d be little need to build a regulatory system with registration and operator licensing. But you canâ(TM)t tell by glancing at a two wheel electric vehicle exactly where on the bike to motorcycle spectrum it falls; that depends on the motor specification and software settings. So as these things become more popular, I donâ(TM)t see any alternative to having a registration and inspection system for all of them, with regulatory categories and restrictions based on the weight and hardware performance limitations of the vehicle. Otherwise youâ(TM)ll have more of the worst case weâ(TM)re already seeing: preteen kids riding what are essentially electric motorcycles that weigh as much as they do because the parents think those things are âoebikesâ and therefore appropriate toys.

Comment Re:Should be a CPSC order (Score 1) 29

Vapes with replaceable 18650 tend to be higher quality and use safer IMR batteries (which also have lower internal resistance for a higher performance vape). Vape pens tend to be lower quality disposables powered by whatever was cheap when battery stocks got low at the factory. In part, that's because few will see the sealed in no-name battery.

Note that the popular 18650 is a little longer and thinner than a C battery and won't even fit in a vape pen. They're not absolutely impossible to short with keys but it's a bit of a challenge. The terminals are on opposite ends of a 65mm cylinder, not a quarter inch apart. They make silicone rubber socks that fit over the ends of spare 18650 batteries.

Many camera batteries are crazy over-priced and proprietary. To be fair, others are much more reasonable but still tend towards proprietary.

So yes, let's keep the red tape brigade on a leash for now. Let it get involved with SPECIFIC demonstrated problematic products.

That depends on the formulation of the battery. There are several.

The problems tend to happen with the batteries that maximize capacity over safety crammed into a too-small space with cheap or absent protection circuitry.

Let's not roll out the red tape brigade prematurely here, it harms innovation and makes everything more expensive. For example, you can greatly reduce costs and regulatory friction with little effect on safety by exempting removable batteries (for example, camera batteries, flashlights with 18650 batteries). Those tend to be better quality and be better protected from damage. They're also avoided by the manufacturers that want to pinch every penny even at the cost of safety and reliability.

Meanwhile, 50 incidents only seems like a lot until you consider how many million person-flights there have been this year. That's not a call to do nothing, but most of this can be handled by air liners having a small metal box and an oven mitt on board. Also a place for the box next to an air outlet.

That's the press doing its usual lousy job of communicating science.

The predictions aren't absolute, they are sets of scenarios for which probabilities are calculated. The longer we drag our feet, the more the set of plausible outcomes narrows. Take Syria -- Syria was a wheat exporter in 1990, but since 2008 or so has been unable to grow enough wheat to feed itself because of climate change when it had become dependent upon imports from Russia and Ukraine. This was early enough that likely we could not have prevented it even if we heeded early warnings in the 1990s when the current scientific picture solidified. We're not going to lose the entire planet in one go, it's going to be one vulnerable population after another.

It may seem like the climate crisis has completely fizzled to you, living in a large, wealthy, and heretofore politically stable country, but it is catastrophic for the people who have got caught. That's how the climate crisis is going to unfold: the rich and comfortable will be able to adapt to the continually changing status quo by moving their financial assets and supply chains out of the way, although you may be paying more for coffee.

At this point it's a matter of degree; we can't avoid problems now like countries being destabilized by climate change and generating millions of refugees. The question is how fast and how big a problem we'll have.
