Big fan of advice like this.

I've been curious about the Delta Force for a while, and I am wondering if there's some sort of training available for civilians that could give you at least a glimpse of the preparation they go through. I'm sure there are many, but I've never heard anything particularly good about one in particular.

Any suggestions based on personal experience?

To be clear: main reason I'm interested in this is simply because it's the kind of preparation that could help you in case you find yourself in a very rare, but potentially lethal, situation (e.g. someone attacking you with a knife in a dead alley, or stuff like this - not the best example but you get the idea).

This article's thesis seems to be that medical professionals are not incentized to provide the best interventions, and as a result, wouldn't pay for this service. However, what the author fails to mention is the competitors in this space that are successful, such as Up To Date, which provides really high-quality research trial data: https://www.uptodate.com/home

Rather than building a product that informs medical professionals about effective interventions, I wonder if the creator would have had more success if he deeply explored what sources of information these medical professionals pay for now - do they pay for anything at all, such as UpToDate, and don't want to pay this because it's an additional expense? If the creator found which sources people are using, the creator could sell this database as a feature for these partners and widely disseminate this data through partner channels rather than creating a competing source of information. It seems to be a case of this being a good instance of a B2B2C model, where selling this service to other businesses that sell directly to medical professionals could be more viable than trying to sell directly to them.

Alternatively, if the creator wanted to sell to patients, rather than medical professionals, the blueprint here is all of the consumer reports companies, such as Wirecutter, which is one of the New York Times's most popular services. Here, again, a "Wirecutter for medical interventions" could be quite successful, and you could sell this service to media companies that provide consumer reports as a service that would bolster these companies.

It's bad the creator wasn't able to find traction, as getting more medical data into the hands of consumers could have a huge postive impact over time.

  I can do all these things already.

You're absolutely right, but just like you can send a letter in the mail, email does the same thing but is digitally native to the internet.

Up until the invention of Bitcoin, there was ZERO scalable way for me @joeblau to send you @louwrentius money the way I send an email. By that, I mean the only thing I need to rely on is a protocol (like SMTP) and you'll receive it.

  What problem / which problems are being solved here?

The problem is that money (paper money/currency) is not the only thing that has value which human beings transfer among each other. We share music, art, poetry, equity in companies, ideas, code, etc. What Ethereum does is take the idea of "Digital trustless money transfer" and expands it to "Digital trustless value transfer"

  I don't understand what this means. What does this do for real-life applications?

Let's say I own TSLA stock and I want to sell it to you. I can't, without going through a middle-person. I need to send my shares to a brokerage (they take cuts and fees and do insider trading crap that they disguise as legal) then you buy the shares from then.

If it's mine, why can't I just transfer the shares straight to you for the listed price (Currently $567.60)? Because there is no platform digital trustless value transfer that will ensure that we both get what we want: Me getting the money, and you getting the shares.
