No. Because they had insights.

Jeff Bezos's insight was that he could slash wasted effort in purchases, via internet + clever algorithms.

Elon Musk's insight was that WE should tell our bank to pay a seller, not give the seller our account details and ask THEM to take the money
Actually I don't think she is so foolish as to believe her own soundbite.

I think she is just saying this to appeal to not-very-bright people who have failed to understand that life is not a zero-sum game.
Billionaires like these 2 exist because they have been right, many many times, when the rest of us were wrong.

And UNLIKE billionaires who gained their wealth by gambling, these ones gained their wealth by providing things that people wanted.
Every $ they have, is a $ someone paid them because that someone preferred to do that than do the alternative, which would be:

(a) Pay for something online and be unsure if or when it would be delivered

(b) Hand over their card details to an unknown merchant.

What is unusual about Guinea-Bissau, nestled between Senegal and Guinea?

(Hat tip to Joe Schmoe MD, @joeschm80238897)
Well, you know how you and I and everyone's brother-in-law are all talking crap on Twitter about how effective or ineffective face coverings are, yeh?

Well, the WHO is actually doing a trial in Guinea-Bissau.

Guess how many patients they need?

This is a REALLY good question!

Let's assume all tests are perfectly accurate, for simplicity's sake.

And let's ignore the word "up to", again for simplicity's sake.

What does this statistic mean?
Does this mean that:
Well I am glad nobody has voted yet.

Because all the answers are wrong.

Let me highlight the relevant words in the question, for people who read it too carelessly.

Some people seem to think I am the world expert on everything. I used to tell my daughter that, when she was 3, and she believed me.

As it is quite flattering to see that grown adults similarly gullible, I shall attempt to answer.

And the specific question is what I think of this Norwegian person's comment.
I don't know what "incorrect use" means.

It is obviously unwise to use the masks as a meal.

The same way viruses evolve. and much faster, because the selection pressure is greater.

This one has a three-phase mutation.

ORIGIN. Doctor tells something to family. (Their relative ultimately dies and understandably they were not taking notes verbatim for later accuracy).

VULNERABLE POINT 1. Family relays something to Newspaper.
VULNERABLE POINT 2. Journalist interprets that to the best of their ability and publishes article.

Cardiology registrars or consultants wanting Cardiac CT to level 2 might be interested in this 6-day hands-on small-group course.

Sadly there will be no reasonable punishment for mistakes, such as public humiliation or twittersassination..

Cruelly, Ben Ariff, who is course director, refused my offer of a lecture on "How to make up your data and not get caught."

"There's no need for that sort of thing!", he hastily replies.
I beg to differ.

On an unrelated note, have a look at this for a sizzler of a story!

Pranev Sharma @psmedic is outrageously impudent to our duly elected medical overlords. Image
Read more of his disrespectful commentary here:

heartandmetabolism.com/wp-content/upl…

And if you are standing for election for president of a medical society, read it carefully and do the exact opposite of what he says.
A side benefit of this issue of Heart and Metabolism is this interesting article on AI and Echo from Tom Marwick's group. Image
