I'm sorry, but making a desktop app look like a phone app doesn't really "improve the user experience" by default. I've been using itunes for 6 or 7 years now, and i literally stood there for 5 minutes trying to figure out what the hell i was looking at when it first started up.
Your missing the point that owning part of a company for 10 seconds brings zero social value to the economy. Which I also tend to agree with. Slightly off-topic from the point of the article, which was that he achieved it without backing of a fairly large institution.
I didn't miss that point - I just chose not to address it. Lots of things add zero (or negative) social value to the economy including Farmville or the gazillionth Instagram clone. That doesn't mean they're not worth doing.
And HFT or day-trading does bring some value to the world. It enables companies to go to the public markets and raise capital. And investors to sell their shares without having to wait too long for a buyer. But those positives come along with negatives as well.
True it adds no social value, but it is arguably the ultimate hacker's game :) You can actually add a little social value by placing only orders that increase liquidity; those where someone else "takes out" your standing offer or bid. That and the fact that your profits are taxed as ordinary income in the US for equities at least.
This is not even close to an accurate summary. He never stated that he had any employer backing, and he wasn't collecting market making fees. In fact he was paying brokerage fees which is the exact opposite.
An employee of what? He states above that he was paying roughly $200/month for a server and $1800/month for the software/data connections to his broker.
I get tired of the "Don't hate the player, hate the game" mantra after a certain point though. We make the damn game. And if the players are assholes, the game is going to suck.
Of course it's a marketing play. Why else would a company willingly commit large sums of money to a completely unrelated business venture. And anyone who was watching the feed before and after the jump will know they did do plenty of back-story on Joe Kittinger and his original mission.
So maybe they should have called it. "3 problems that raytracing can't solve, and 4 other ones that just suck about modeling real life in 3d(on a 2d surface)".
