What are my chances at 2nd-tier math and cs schools like Cornell, Northwestern, and UMich?

^Yes, it’s not a brand new trend, and that’s why its effect has already been felt. If we don’t reverse that trend, implications will be more severe. US lead in high technologies is not a given. We’re falling behind in 5G. Silicon Valley is sliding and no longer the most innovative place in the world. Here’re just two of the articles I read this morning:

https://www.nytimes.com/2019/07/01/business/dealbook/huawei-5g-national-security-trade.html
The second article didn’t make the connection to education, but the connection is there.
