My dad shared this with me. At first glance, it seems informative, so here's my summary:
It's an hour long, had it not been my Chinese de-proving, I would have finished this in 20-30mins. But it was fun looking up and learn modern Chinese terms.
邀请吴晓波、周轶君、吕廷杰、马家辉共话“跨越”主题
3 primary resources on communications:
1. Spectrum 频谱 (frequency 频率 reservations)
2. numbers
3. Satellite orbital reservations
5G = IMT2020 (International Mobile Telecommunication 2020)
Every 10 years, a level of G. 1990 = 2G, 2000 = 3G, etc.
China's radiation approval limit is only U.S.'s 1/50.
Since higher freq. (viz. 5G) means shorter distance, thus needs more towers.
It's possible to build a 5G hybrid on a 4G network, but with some limitations, such as: can't reach time delay of 1 ms (our nerve synapse travels at around 10 ms to the brain), can't do 1,000,000 connections every km square, etc. Thus, true 5G must be built independently, viz. SA.
In Blockchain of Bitcoins, 5G's speed helps avoid long global update of the an account's savings.
Odd level 1G, 3G, 5G are revolutionary upgrades. 2G, 4G are merely forced.
1G problem, crosstalk problem.
2G digitized. Solved crosstalking problem.
3G Web capable.
The rest of the talk is philosophical discussion, ie. possibility of A.I. like terminators, Matrix, man should be master of technology or the other way around, Musk's TESLA, etc.
Interesting intro to Daniel Kahneman's thoughts (possibly from his book "Thinking, Fast and Slow") on two system of thoughts: 1. Fast, emotional, instinctive. 2. Slow, analytical. If strong on #1, then one is easily affected by the fades.
