I have never argued against spending money on basic research. Also, like who died and made you the normative arbiter of what's waste and not waste?
The government is not very good at commercializing technology.
Look at the best 'hard tech' companies coming out of China - Huawei, United Imaging, Inovance, BYD, CATL - which one of those are government owned/operated?
Given that you raised the point about benefiting the rich - are you suggesting that the billionaire founders of these companies (Ren Zhengfei, Xue Min, Zhu Xinming, Wang Chuanfu, Zeng Yuqun) wouldn't benefit from your so called 'stimulus to the engineers'?
On your last point, if you are of the view that the government should decide what people want or not want to buy you should live in North Korea - or if you have a time machine, the USSR.
Oh this is a long story, but it depends. And this is something that has to get worked out.
I'm not sure about the media, but the visa-free travel has been the best policy decision in 2023/2024 - and much more effective than the stupid Confucius Institutes at promoting what China is like.
