Newest phones (like iPhone 8) work with GPS, Galileo, Glonass, and QZSS. Beidou support will come in the future.
Note you can buy off-the-shelf GPS modules today that will work across all four GNSS: https://www.u-blox.com/en/product/neo-m8-series
>... even precision missiles. So if GPS were to be jammed, or disabled by a hack into the ground control systems -- PLA missiles would still work just fine. Hmm.
Earlier quoted context omitted.
>So China has the technology to destroy satellites [ Any country that can launch a satellite has a technology to destroy one. It's called a missile. You don't even need to go to orbit - just intersect the orbit of the target and dump a bucket of nails in its path.

Exactly. At the moment, the consumers benefit from the increased accuracy and coverage provided by multiple GNSS. Sidenote: the ublox M8 chips are a pleasure to work with, and there are variants that have IMUs (gyros and accelerometers) on board for sensor fusion. All for <10$. What an exciting time we live in!
"We are likely to see an increased bifurcation of the world into two camps - 'pro-China' and 'pro-US'", says Blaine Curcio, founder of Orbital Gateway Consulting Why do some people view it as a with-us-or-against-us problem? Combining beidou with GPS gives a better accuracy. Some competition and collaboration in the GPS field can benefit us as a whole.

I wouldn't want to be navigating critical transportation during a dispute between China and the United States with this track record (would you?): http://fortune.com/2018/08/28/china-has-been-withholding-bir... https://www.wired.com/story/australias-ban-on-huawei-is-just... https://nypost.com/2018/09/19/chinas-social-credit-system-is... http://fortune.com/2016/05/20/chinese-social-manipulation/
Why is 'rival' quoted?
Let's hope even more countries get into GPS "rivalry."
