The article actually does mention using this technique, though it doesn't explain it, so thanks for the background from someone who isn't familiar with this space!
Yes, one might argue it's a little misleading, but it comes across as significantly more genuine and less scammy than TurboTax. The federal filing is completely free, no matter which forms you have, and you just pay $15 per state. They also have the standard support upsells, but they don't push them crazy hard (I think it's one prompt between the federal and state sections).
I've used them for the past several years, never had any issues. Paid for audit defense one year when my return was especially complex (luckily haven't needed it yet).
In no way does it set a dangerous precedent. Fortifying flour and iodizing salt (both of which could be termed a "medical treatment") were huge successes, with universally positive results and at virtually no cost. Mandating something like this should be done cautiously (in either direction), but fluoride isn't the first, only, or last example of it.
The only difference is that it's rather harder to avoid fluorinated water than iodized salt if one is so inclined, which raises the bar for proof of efficacy and preponderance evidence that it does not cause harm (which has been provided by others in this thread).
I was under the impression it was more of a distribution problem than a quantity problem? This chart suggests we're building on the order of 1.5 million units of housing per year, which (unless all of those people are occupying a single unit each) should be sufficient in aggregate to keep up with population growth: https://fred.stlouisfed.org/series/ETOTALUSQ176N
But people are moving to the cities, which is exactly where we're not building.
Also a firmware engineer. I see 4 career paths under the advent of AI:
1. If you can't beat em, join em - get a masters in ML or something and work at a higher level of the stack. I know several folks who have pivoted this way and are happy.
2. Double down - there will always be layers below the AI (drivers, silicon, etc). Sure, ChatGPT will continue chipping away at how much coding we do day to day, but at the end of the day, good luck to an AI trying to debug I2C bus clock stretching issues IRL. And you can bet that these robotic actuators have plenty of hardware issues to debug.
3. Pick an area of tech which is relatively immune (medical/automotive/aerospace) due to regulatory and other barriers to AI entry. You don't necessarily need robotics/CV experience to do this.
4. GTFO (I say this with no judgment) - and work in a different industry which is less likely to be automated. It would not be the most lucrative option but is certainly an option.
Also curious what "50%" means in their specs; the top power for the motor is 250W and top speed of 25kph would take ~100W on flat ground, which would throw off your calculations considerably. (Not that I take issue with your calculations, they just haven't published enough data to know what you'd actually be getting.)
More than happy to learn something through a mistake in my calculations !
Regarding the 50%, I assumed that they stated this number because this is when the battery is in bulk charge and can suck up as much as you can give it.
For the 250W, I hadn't even seen that, good catch. Maybe 250W is the peak power that cannot be sustained for thermal or current rating reasons ? 250W for a 12.8V 10Ah battery is 2C, so that should not be the limiting factor. I do not know about the motor or the ESC
Also, for sure the maximum range is not achieved with the top speed !
Agreed on all points! Very plausible that 250W is peak; other motors on the market vary whether they state peak or sustained so the waters are a little muddy (e.g. I know that the popular BBS02 "750W" motor can put out over 1kW peak).
This is an interesting alternative to existing kits where you need to replace a wheel (hub-drive) or do surgery on your bottom bracket (typical mid-drive). It also appears to not need an external charger (the charge port appears to be a universal C14, the same as a computer) which is very convenient.
On the downsides, I have severe doubts over the battery cell quality at that price point, and it looks significantly heavier than other options from the metal case alone (I don't see actual specs for weight).
Love the demo video. The mud and fire scenes made me cringe, which I'm sure is exactly what they were going for (as the motor keeps spinning regardless of the foul treatment)!
I will keep my standard mid-drive conversion kit (I've used TSDZ2 and DM-02 in the past) but always love to see alternatives coming online for other segments of the market.
It's difficult to explain without spoilers... one of the characters feels significantly more fleshed out and real because of some artistic choices in the voice acting.
I am not sure I'd go as far as GP and say that the book is not good, but this is one of the cases where the audiobook feels more like a "production" and not just a book in a different medium.
