  • 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.





  • My point was the timing. It wasn’t good for any other candidates but the incumbent.

    Even if we did voted for Harris as VP, that was 4 years ago. Democracy is not just about a one-time voting, but having regular elections every 4 years. I may have voted for Harris as the VP as part of the ticket, but I should be allowed to change my mind 4 years later to vote for someone else.

    One of my biggest gripes about our two-party system is the lack of competition within both parties. Every 4 years, we are presented with candidates from each respective party and then we’re asked choose the “lesser of the two evils”. It sucks.




  • 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”.


  • State university tuition in the 90’s was about $1500 a semester. I worked a summer job for $6.50/hr and was able to earn about $1000 (before taxes) in a month. I didn’t work for the rest of the summer because I still wanted a bit of a summer break :) But it is absolutely possible back then to work a little part time, then full time in the summer to pay for college. Then you can bootstrap yourself into a career.

    Right now, jobs don’t really pay any much more, but tuition is 10X or more. Unless parents pitch in, Its impossible for young people to get higher education w/o going into massive debt. I say go into trades and self-employment, it may be a better option nowadays!
