An immigrant visa is basically the same thing as a green card, i.e. permanent legal residency. Once you have an immigrant visa, you can enter the US and receive your green card in the mail a few weeks later with no additional work. After five years, you can apply for citizenship. You have unlimited rights to work and live in the US.
However, ignoring family-sponsored routes, it is extremely difficult to get an immigrant visa in the first place, usually requiring years + $10k+ of fees to work your way up to it. You also need a sponsor to pay the fees (legally, you can't pay it yourself). Therefore, the vast majority of people start on a non-immigrant (temporary, restricted employment) visa and eventually ask their employer to sponsor a green card.
When people say "if you wanted to immigrate, you should just get an immigrant visa", they usually assume any other route is a hack or loophole. But it's actually the most common way to immigrate by far. You can, of course, interview for a job from abroad and ask the employer to directly sponsor an immigrant visa, but they'd have to wait years (best case) until you could actually step foot in their office. Plus they'd be forking over thousands in legal fees for an employee they haven't even seen in person. Nobody would do this, so the commonly accepted way is to bring an employee over as a temporary worker first and then apply for a green card while they're in the country.
By the way, the same checks apply for immigrant visa applications both inside and outside the US. You might think that employers are scamming the government by turning purported temporary immigrants into permanent ones, but the exact same qualifications checks, eligibility requirements, waitlists and quotas apply if you do the process inside vs. outside the US. It's entirely possible, and common, for green card applications to get denied (and the applicant's location doesn't factor in to this).
Every tech company could not exist without the internet, developed by the US government/universities and released for free. Should they all be nationalized? Are they all "raping public resources"?
Open-source developers have plenty of ways to make money from their work. You can even stipulate in your license that companies who use the code to make more than a certain amount of money pay a fee. If developers choose not to do that, that's fine, but it means nobody is obligated to pay them.
Imagine Warp donated $1000 to Alacritty. Would you be happy then? What about $10k, or $1 million? What would be the appropriate compensation? Sure, Warp wouldn't exist without Alacritty, but they also wouldn't exist without the ARPANET. At the same time, Alacritty's developers didn't raise $50 million in funding, pay developers to build Warp's features, or do any of the marketing. How do we know how to compensate them? Answer: we look at Alacritty's licensing terms, which explicitly permit free use of the software as long the license is included in all copies (which the Warp devs have complied with).
It appears he is selling a service where he comes to you (optionally with a Mac Mini which is probably why he's buying multiple) and sets up OpenClaw for you.
They definitely do. A common configuration is running a supervisor model in the cloud and a much smaller model locally to churn on long running tasks. This frees Openclaw up to lavishly iterate on tool building without running through too many tokens.
There are few open source projects coming along that let you sell your compute power in a decentralized way. I don't know how genuine some of these are [0] but it could be the reason: people are just trying to make money.
There have been countless projects to sell distributed compute power. I don't know of any that have gotten much traction. Everyone keeps trying to create new ones instead of developing for the existing ones.
The one you linked to looks clearly like a pump-and-dump scam, though.
It doesn't cost $600 in Anthropic credits though. It probably costs a few cents (definitely <$1).
I do understand the general point you're trying to make, but you can't overestimate the cost of tokens by a few orders of magnitude and still expect the logic to hold.
It does make a difference. When filing for adjustment of status, you can request USCIS to consider both you and your spouse as chargable to your spouse's country of birth, and therefore be placed in a more favourable GC queue. This is called cross-chargeability [1].
Because of this, the "100-year green card queue" problem only really applies for a couple who are both born in India/China, with kids who are not born in the US. If even one child was born in the US, they would be able to sponsor both parents for an immediate green card when they turn 21 years old. In the meantime, the H1-B beneficiary can extend their visa indefinitely and port their approved I-140 whenever they switch jobs, with a 6-month grace period. The spouse also has full working rights.
21 years is a long time, but while working, both parents will accumulate social security credits and will be eligible to recieve benefits upon retirement (if they've secured a green card by then).
Donated blood is stored as packed red blood cells, with the plasma removed. The plasma is where most of the hormones reside while being transported, so in packed RBC transfusions, there will almost no transfer of hormones. This makes it so that blood type is pretty much the only important factor when determining whether somebody can receive blood.
Sometimes doctors do perform whole blood transfusion which does not have the blood plasma removed. This has the chance of increasing hormonal levels temporarily in the recipient. However, the body will quickly compensate and bring levels back to normal. Even if not, the hormones will still degrade and lose their effectiveness over time.
Side note: everybody has both male and female hormones in their body, at different levels. These levels can change a lot depending on your age, genetics, menstrual cycle, or even the time of day. As long as there is no prolonged increase in the levels of a particular hormone, there won't be any abnormal effects.
