A good thought experiment is to imagine a hedge fund which invests in the s&p500 all the time, but once per year takes all its capital and sells options with a 5% return and a roughly 1/20 risk of ruin. On average they beat the s&p500 by 5% every year, and only explode once every 20 years on average.
If you could charge 2 and 20 and smoothtalk investors the chances that you get rich before it explodes are pretty good.
Differentiating an investment with a negligible chance of going to zero (like the s&p500) from one with a small but nonzero chance is difficult until one of them explodes.
Medtech is annoying because of the primary focus being documentation. I spend much of my day writing stuff that noone cares about for people who will never read it. Doing this on paper is slow. Doing it on a computer is even slower. Finding a terminal and filling in structured forms is a pain in the ass when I want to be seeing patients, doing procedures etc. Using things like google glass and offsite scribes is a good way to do this.
At least the Saudis are now diversifying into western markets with their capital. Which they are quickly learning comes with some social and moral constraints that have been largely invisible in the diplomatic/political world.
The finance and tech world doesn't need to compromise for some vague fragile security arrangement in the middle east. But regardless money is money and it will find an immoral taker at some point. The best we can do is keep the pressure on companies to hold their investors accountable.
That said, I'm not a fan of bringing the fanatical political tribalism, which is very popular in the US at the moment, into the tech/business world.
What social and moral constraints exactly? They invest money through SoftBank, reap the dividends, and then spend it on wars and oppression just like before. It's fine to just admit that the tech world has shaky morals. But utterly delusional to think that investing in tech will somehow make Saudis more pliant.
I want to upvote you, but I'm afraid you're mostly dreaming. What companies have refused Saudi money? Maybe a few do, but there's plenty of other takers (talking about startups and hedge funds - it's almost impossible for a publicly traded company to "refuse" an investor I think).
Time dilation: At a constant acceleration of 1g, 100k galactic time reduces to 12 years ship time. Cf the link provided in the comment you're replying to.
As you approach the speed of light, the time observed by the traveler ticks slower, so you can travel vast distances in short observed time periods. So the people on the ship would spend 12 years, a manageable time period, but us more or less stationary observers would still see 100000 years pass.
Not if the exchange has spreads and leverage. Even small spreads can screw your odds completely if you trade at margin, and gamblers bust means if you turn over your money a few times at high leverage you'll probably lose it all.
