  • You could spend the money, but you also need to consider whether that money is well spent. Batteries do not last forever. Maybe that money is better spent on R&D to develop better batteries first. Also natural resources and environmental impact needs to be considered. Batteries take natural resources to build and also occupies a lot of space.

    20 years ago, we also have the technology to run AI workloads. Except we probably had to deploy billions of CPUs to match the capability of today’s GPUs. We have the technology then, but it is not practical. And that money was much better spent in the R&D that lead to today’s GPUs. So similarly our batteries probably needs to be a few magnitude better than what we have today before it is practical to use.


  • You need to consider more than just solar farms. There are many roof top solar systems on people’s houses. That’s what I’m referring to regarding logistical nightmare.

    Second, if we are just going to cover up solar panels, then it really defeats the purpose of having it. A better way is to come up with ways to store this excess energy to use when there is low production and not have to depend on fossil fuels at night.



  • Yep! There’s a surplus of educated women, who are too educated / accomplished in their careers to want to marry uneducated rural men. And many of them also deferred marriage for their education and career and thus became a bit too old to bear children. All of this just exacerbates the male to female ratio problem in China, which is also a huge problem for China’s demographics.

    China is going to shrink in population, Japan, Korea, Taiwan also have these problems.



  • I’ve always thought that trying to address DEI from the top-down is never the right way to do it. This include college admissions. All it actually does is promote unfairness and a non-meritocracy. It takes many years of training to learn the skills needed for certain jobs. Hiring someone because of their skin color instead of their qualifications can actually hurt the bottom line (and top line) and just leads to more resentment. And it also really cheapens and damages the reputation of the minorities who actually worked and earned their way to their spot. Had a super smart Nigerian friend who is a medical doctor who finished very high up in rankings in medical school. But because of DEI policies, people will always wonder if he got to his place because of “quotas”.






  • Just came back from Tokyo. Tokyo’s public transportation is awesome. You do also need to walk a lot at times and the first few days our legs were quite sore. But towards the end of the trip I can feel my leg strength again, felt healthier, and did not miss my car at all. To go to certain places, you do have to plan a little bit ahead, for example, a day trip out to Mt. Fuji area requires booking tickets because right now there’s a ton of tourists. But within the city, the subways are so convenient.
