Heterogeneous architecture FPGA (580MHz)+Qualcore DSP (1.2GHz)+16G DDR, all chips, all components made in China ($130), in US, similar products >$500. This was a dream 2 yrs ago. Remember small-hand Rubio's tweet about FPGA and Huawei back in 2019?

@patricia_m_kim @ForeignAffairs "no loyalty or lasting influence"... LOL a joke from a self-declared "China expert". What America created is dependence, not loyalty. Once you pull your $, "loyalty" goes away.

@noahkostesku I did PhD at UofT, when I was a TA for engineering science, the UofT kids were not near as intelligent as I thought. So, this is a joke.

@suanguaa 好莱坞拍了96 部朝战的影视作品， 有不少是揍志愿军的， 他们还拍过揍毛主席的作品 (The Chairman ), 只是国内不让放。韩国也拍了不少揍志愿军的电影，《白马战役》,《高地战》获得奥斯卡最佳外语片提名资格。他们通常强调战争的残酷，没有像国内拍的傻逼斗狠的电影， 为保护一块红布，浪费几十条人命

@NEO_Diver 中国的大学生到印度也是高中生，没办法，穷山饿水出刁民。

@RichardMeyerDC I mean they are light year ahead of America, thanks to all the "consultants, strategists, podcasters" i.e., people like you.

@Armstrongrr2m 中国人做题考大学没问题，只是做的题90%没有用。我高中是数学和物理的学霸，那种初等数学的奇技淫巧对以后的科研一点都没用。国人心目中的数学大神韦东奕写的文章只不过是三流水平。

@szygls 为什么我买 FJPNX从2025的$16.3 涨到昨天$24.01，MCHFX 从2025的$15.31只 涨到昨天$17.14. 是不是国内的人都被房地产崩盘逼疯了。

@xiao5087 台灣爆量生產怎么可能超过中国？

[epr_sci @epr_sci]

@pepeniub 这个我同意，在中国什么都便宜，性价比最高的是人矿，人矿里性价比最高的是化学工程师。我以前在国内雇硬件工程师是美国的1/5，我最近在国内雇化学工程师是美国的1/11.

@wangjupaian 我女儿11年级，为参加AMC回国2个暑假请人辅导，她昨天做两个小时，拿到133， 挺不开心. 我告诉她的AP Calculus BC 的A+ 和她400米跑55秒绝对秒杀考150的书呆子。

[epr_sci @epr_sci]

@shangguanluan 我给我女儿做，她在国内接受过2次math summer camp,基本能做，我告诉她再深专这些奇技淫巧根本没用。国内70%的高中学习要不是死记硬背就是这种没用的刷题。她幸好没浪费时间。

@kinglinzhuhui I am wondering why China wants to do that. It gets absolutely no return. China should just sell agricultural supplies and fuel to them at market prices.

@dgxinyang @ni1hannah 我给我女儿做，她在国内接受过2次math summer camp,基本能做，我告诉她再深专这些奇技淫巧根本没用。国内70%的高中学习要不是死记硬背就是这种没有的刷题。她幸好没浪费时间。
