There's a tendency to overrate the talent at these well known companies. Remember, LinkedIn didn't salt its passwords...

I know plenty of people that salt their passwords, that doesn't mean they have the talent to build a LinkedIn or even realize that the need existed. There's a lot to be said for vision and execution. Attention to every detail has nothing to do with talent. Every single programmer in the history of the world, talented or not makes mistakes, that doesn't reduce their talent. Talent isn't just about technical perfection. While LinkedIn didn't salt their passwords, how many other big-deal innovations did they execute and accomplish?

And an even worse tendency to assume those with the most successful careers are the most talented.

So? they're worth billions.

What does that have to do with anything mentioned here?
