  • Do you think intergalactic travel will ever be possible?

    Jump

  • 300 light year is the planet direct neighbourhood, not intergalactic.

  • What technologies are constant failures but we can't stop trying to make work?

    Jump

  • Nobody said supra conductors ?

    While being used in some niche field (mostly MRI) the ultra-low temperature needed means there is only very few case where the price of cryo-cooler offset the elecricity costs

  • What technologies are constant failures but we can't stop trying to make work?

    Jump

  • I've seen a road map at the start of iter which was actually more. 30 years to get a stable exo energetic plasma, then 30 years to build a demonstrator able to produce electricity, and then 30 years to have industrialised fusion plant.

    Jump

  • The thing is how is a flying car different from a aircraft?

    We have (ultra) light aircraft not much more expensive than a good car, we have helicopter with vtol abilities. Licencing isn't that more complex than for a car.

    The problem are the maintenance cost as a failure would be dramatic, and the noise meaning people don't want them over their bacxyard/balcony

  • Do you think intergalactic travel will ever be possible?

    Jump

  • The very slow is the issue. Assuming we can reach 10-20% of c, we can reach a couple of nearby stars in 200 years (Wikipedia gives me 50 stars with 30 ly).

    200 years is roughly the time from the Napoleonic era from today (Taking an Euro reference). Do you remember what your ancestor were doing during Napoleon Russian campaign or when US purchased Louisiana?

    Society changed massively since Napoleon. Over 200 years the society culture of a generation ship would also drastically diverge from ours. Moreover, I can't think of many piece of technology which can keep working for 200 years without a few massive overall.

    Jump

  • I know enough physics to say no Even inter-Stellar is out of our reach (without generation ship).

    We have zero reason to believe in an effective way to build wormhole, jump gates or anything similar. Even high energy cosmic rays have a limited range (due to collision with photons) which is a strong clue that there is no shortcut in space

  • What is something you can't do with 100M dollars but can do with 1B dollars?

    Jump

  • While I can see many things with price tags well above 100 Million US$. Like planes, hospital, semi conductor lythography machine. A single person owning them is a problem per se.

    Moreover, almost every serious project of super rich net worth tax isn't capping your wealth, but just making sure you pay 1-2% of your net worth as takes which is still way less than everyone else, and won't prevent you to get richer investment capital growth.

    Mini stories on lemmy, will it be interesting?

    Jump

  • Go for-it. (Or even share link to a "centralized platform") we need more content here

    Trans athlete of Lemmy, how do you manage the locker-room transition ?

  • Depending who you ask,

    Compared to a teen ? It's old

    Compared to a fresh retiree ? It's young

    To be the father of a 18 yeard old kid ? That's prettty young

    Objectively it's prime adulthood

  • If abortion gets legalized, then renouncing paternity should be allowed too, to ensure equality?

    Jump

  • There is moment where biology comes into play. Pregnancy has major consequences for the person being pregnant . Not for The father, and once the kid is born, laws protects the kid. Having unprotected sex comes with risk, pretty minor compared to BASE jumping or riding a motorcycle but it can have massive lifelong consequences.

    While technically illegal, men abandoning their kids aren't that uncommon. They're far on the asshole scale but they exist

  • Considering you do computer science not business/sales/purchasing you won't be the face of the company, but one of the many underpaid corporate slave in a big open space.

    They won't care about an underwear photoshoot. Especially done in a professional contest

    Places to increase a image's quality (without using AI)?

    Jump

  • Define "AI" because any algorithm to upsample data and correct "compression artcfact" is generating/guessingdata to fill the gap.

    Now, at which point does it stops being "interpolation" and does it become gen "AI"? That's a philosophical question.

    is it embarrassing to graduate college at 24?

    Jump

  • Isn't it pretty standard ? Finish high school at 18 + 5 years to get a master is already 23, so 24 would be a year late, that's absolutely fine. Let's say you retook a year to get better ranking, then spend a year as an exchange student abroad but failed due to language issue, it's already graduating at 25. Let alone if you work aside the university which can mean you fail each year once.

  • Would you play a slow game today?

    Jump

  • Sometimes, I want to retry Stellar Crisis, at least for it's historical value But feel like the era of small pb(e)m and similar is over.

    Still consider trying the de profundis rpg, but it's more a weird object on my gameshelves than an actual game

    Do you think people will live to the year 2100?

    Jump

  • Kids born today will be 75 in 2100, which at the current state of things will be too young to retire.

    Even if there is a major catastrophic, people in the Roman or medieval era made it to 80, it was less common than today, but wasn't unheard of either

  • Do billionaires have most of their income taxed as ordinary income or capital gains?

    Jump

  • Many actually don’t, they don’t convert (much) the capital to money, so they avoid capital gain-tax (which tends to have exception for business owner and long term holder), often they use company asset (like an average worker gets a phone, a laptop and sometimes a car, but they get a boat, a jet, and a nice house on the company budget), borrow money against stock, and actually don’t need that much of their actual money (remember that a billion is huge we don’t talk about getting a nice house, and a private jet, but multiple airliner, and a brand-new top notch hospital in the centre of an expensive city, including all worker wage for a while).

    This is why so many people support a net worth tax like if you pay less than 2% of your net worth in regular tax, then you get an extra tax to reach these 2%
