So are Europeans and Latinos and Americans and Arabs and Africans and dolphins.
The discussion isn't about race. It's about creating a culture and ecosystem of innovation. Which even other cities in the US have failed to replicate beyond modest successes.
It might as well read "Silicon Valley may well be a 7, but Asia is on its way with a couple of 2s and 3s."
What it actually talks about is 'large companies are opening more satellite offices around the world than in Silicon Valley in the last few years'.
The appropriate response to this article is: 'so what? How does that matter?'
Just like the rest of the world starting large universities has rarely had a negative effect on institutions like Oxford, Harvard or MIT, the rest of the world starting innovation center is unlikely to do much negatively to Silicon Valley.
Starting an 'innovation center' and actually creating lots of innovative companies (including some really large ones) are not the same thing at all. In fact, just like IITs are a great feeder into MIT or Stanford, some of the best companies outside Silicon Valley have become a feeder for the SV ecosystem.
I'm not saying it can't happen. I'm just saying quantity is not the same as quality, and quality innovation center is very hard to create without lots of quality people in all parts of the ecosystem.
It's much less efficient for both YC and individuals if every interested individual started emailing and asking for updates. Much better this way - after all that's why broadcast or pub-sub systems exist. HN is kind of a curated broadcast system.
It often happens that people who're working on the project might not find 'right now' to be the ideal time to share updates. This could be either because they're immersed thinking through a particularly challenging aspect of the problem/solution, or they feel a little lost (which is a normal feeling in the middle of ambitious projects). Sharing an update at that point makes you feel vulnerable, but that's exactly what you need to do.
Or it could be that they have a really promising angle and want to see more data before writing something up. The 'more data' approach is usually a mirage (promising approaches start showing potential even at early stages/small scale) and sharing progress helps the project even in that case. (For example, you might learn that a similar approach has been tried before, and here is what someone learnt).
Something genuinely nice/caring at the place I work now was the Wednesday before Thanksgiving where they just told everyone to go home after lunch and enjoy the long weekend.
Lee Iacocca was an engineer.
Elon Musk is not an engineer.
maybe not, but pretty technical.
A better example of a non-tech CEO of a tech company is Jack Ma, who was an English teacher.
