  • Besides the first all electric train bit, which is nonsense, it also touts the capacity of the train. It has 120 seats, which may be mind blowing to car heads, but for a train is rather on the low side. Regular passenger trains often have over 200 seats and many have more seats for the same length. For busy pieces of track 600 seats per train aren’t unusual.

    It really is like the author has never heard of trains before and has his mind blown by the concept.

    Personally I think putting in batteries is kinda dumb, trains need so much infrastructure already and it’s fixed in location. Adding a power delivery system (like overhead power lines like most electric trains have) is really easy. That way a lot of weight is saved, thus making the whole thing more efficient. You also don’t need any special materials to make it, compared with huge batteries. And the wear components are a lot less expensive to replace.



  • That’s within a solar system, where distance, time lines and energy is relatively low.

    Any event with enough energy for something to leave the solar system, destroys all life, even microscopic. And even if somehow it does survive and leave the solar system, space is pretty much empty so it will probably never hit anything. But if it does hit something, 99% of what’s out there is stars. So it would end up in a star. And if it does hit a planet, coming in at intergalactic speeds absolutely destroys any life. None of that matters though, because the distance involved is so freaking huge, nothing living can survive that long. Travel times are so long, only fossils would arrive, that’s how long we are talking.


  • If aliens were to visit us it’s a miracle not only in space but also in time.

    Space is huge, for some aliens to randomly arrive here would mean they are just about everywhere. We would surely see signs of them in other solar systems, even if they haven’t visited here. There are so many solar systems out there, you don’t just randomly stumble upon ours. And the space in between systems is also so big our brains literally can’t fathom it.

    But time is huge as well. Humans as a civilization with electricity and technology has only existed for 200-300 years (being generous). Some say aliens have only been interested in us since the atom bomb, which is not even 100 years. However humans as a species has existed for over 100,000 years. And intelligent tool users have been around for about 1,000,000 years. If aliens visited anywhere in that time they would have laughed at the silly monkeys and have been on their way. For them to have randomly stumbled upon us just as we are enjoying our few hundred years of modern civilization is one hell of a coincidence.

    Space is mind bogglingly huge, time as well, for both to line up perfectly for aliens to happen upon us is impossible. Even if life is abundant in our galaxy, the separation of time and space pretty much excludes any chance for contact.


  • I’d go one step further. Not only does our current understanding of the universe not include any possibility for FTL, as far as we understand FTL would completely break reality. Science actively excludes FTL as a thing that can exist.

    Wormholes might be an idea, but they aren’t even at the theory level yet. More of a conjecture that fell out of some math, but can’t exist in the real world.


  • Really I’m gonna need a source for that old timey radio claim. Because that sounds like it’s made up and even if it’s not, correlation does not mean causation.

    There is no known mechanism for non ionizing radiation to have ANY effect on the human body or individual cells besides from a warming effect. And even the warming effect is quite small, there are normally a lot of other factors that have a way bigger effect on the temperature. See the Mythbusters episode where they tried to warm a chicken on a radar emitter. The turning of the radar cooled it down more than any warming from the radar did.

    If there is any truth to claims that non ionizing radiation harms humans, physicists would be all over that. That would mean new physics in an area where there hasn’t been any new stuff for a long time now.

    But it turns out we understand it pretty well and see no mechanism for any harm to occur. In that context all of the studies that find no relation are meaningful. If there seems to be no relation and there isn’t a mechanism to do anything, why would anybody think there is anything to find? Turns out it always comes down to FUD, to further some kind of an agenda.


  • I did the exact same. Google Play Music was actually a good service back in the day. I hated it when they turned it into YouTube Music. I complained about all the broken stuff, so they gave me a home speaker for free and upgraded me to YT Premium for a year. After that year I stuck with YT Premium, since it was less than $2 extra. They also fixed a lot of stuff I complained about. Not everything, but a lot of it. I think YT Music was released a bit before it was ready. Now it still has some issues, but is mostly fine.

    Usually I watch 1 or 2 YouTube videos a day and without Premium I would most definitely not. I opened a YouTube video on a computer I wasn’t signed in the other day and it started with a 2 minute unskipable ad about crypto stuff (an obvious scam). So I closed it real fast, no video is worth sitting through that. Even with Premium I still need SponsorBlock. But with that combination watching videos is actually fun.

    Still listen to YouTube Music all day at work, so that’s a good value for money for me.



  • I know a lot of folk that work at MS or have worked there, they are all very good people. They are highly motivated professionals that are top in their field. MS is a rich company and they recruit the best they can. However those are not the people making any kind of decisions. And it’s a cut throat company, if the budget gets cut, you are out on your ass. At least in most of the world, where strong employee protection isn’t a thing.

    Don’t get me wrong, MS has a lot of bad apples just like any other company. Useless managers who say dumb shit and take praise for other peoples work. A leadership that doesn’t care about anything except their bonuses and the bottom line. But at least as far as the engineers go, there’s plenty of really good folk.

    People also seem to forget how huge MS actually is. And a lot of the time the different branches within the company are as far away from each other as can be. Even within the same branch one can only talk to so many people.








  • At a consulting job I did recently they got an AI for a specific task to have an 25% rejection rate. Which I thought was pretty good and the team working on it said there was no way they could do better, this is the absolute best.

    So they went and asked the customers if they would be interested in this feature and how much they would be willing to pay. The response was nobody was willing to pay at all for the feature and a 25% rejection rate was too high.

    The reason customers gave was this meant they still need a human to check the results, so the human is still in the loop. And because the human basically has to do most of if not all of the work to check the result, it didn’t really save that much time. And knowing their people, they will probably slack on the checks, since most are correct. Which then leads to incorrect data going forward. This was simply not something customers wanted, they want to replace the humans and have it do better, not worse.

    And paying for it is out of the question, because so many companies are offering AI for free or close to free. Plus they see it as a cost saving measure and paying for it means it has to save even more time for it to be worth.

    So they put the project on ice for now, hoping the technology improves. The next customer poll they did, AI was the most requested feature. This caused some grumbles.
