I think having some top talent moving to non Silicon Valley companies is a good thing. Computer science and engineering is a driver for our economy and I like the idea of making companies and our infrastructure as strong and as robust as we can.
As much as I appreciate different cultures in different countries around the world and I wish all people peace and a comfortable life spurred by global trade, I would like to see all countries have more robustness and resilience in the face of occasional supply chain problems, world level political strife, etc.
