Sure, you don't want to rely on a lone genius. But I'd argue it's much better to have a team of 10 excellent engineers than 30 mediocre ones.

There are tons of companies with thousands and thousands of engineers who could easily make do with 100-1000 engineers if they were willing to attract and retain top talent.

> And as an interviewer, it is really hard to identify who is 10x and who is not.

That's definitely true, but top companies manage to do it. And when they make a mistake, they rectify it.

Team sports still pay to attract top performers. The best players can be a force multiplier for everyone.
