I am working on Baduk Teacher, which makes having Go lessons (the board game) across different languages possible. The highest level of human Go is predominantly in Korea, China, Japan and Taiwan. Western world is catching up, but the gap is still very huge.

I think the main reason is that the West has quite limited access to pro-level teachers (similar to how chess is like in Asia, just the other way round). Most pro-level Go teachers in Asia do not speak/read any foreign languages (e.g. English), so I want to remove the language barrier and make high level of Go teaching more accessible to the Western world (so that the Go population there will increase). Several European users used it and the feedback was good (and recurring purchases). The translation part is working quite well (Go-specific domain translation), and I hope it will help more foreign Go enthusiasts improve their game.

"You need to learn to observe what’s going on in your mind almost like a third-person observer."

This mindset reminds me of Vipassana. Observe your feelings (or "modes" as OP said), and avoid trying to force yourself to switch from one mode to another because it is unlikely to work.

there is a csv driver[1] which allows you map a csv file on the metabase server, or providing a url of the csv. But I guess most people (including myself) would think of "upload csv file via UI" when it comes to csv support.

I have briefly played with the opensource version of Superset, Metabase and Redash, and ended up choosing Metabase for our use case.

Metabase has the most beautiful and intuitive UI among the three, and works well when your use case is supported, but further customization is difficult. Superset is good for customization, but for setting up some standard chart types/dashboards the effort will be more than Metabase. Redash is sort of in between, and sometimes feel slow.

Not defending indeed. I just had a frustrating experience where Apple refused to repair the 2 manufacturing defects on my MacBook Pro for free (which they said they would on their website [0] [1]), claiming there was corrosion found on the logic board. There is no option for only paying for the part they purportedly said you are responsible for. You have to pay for their malfunctioning parts if they say you should.

What would you choose for a laptop? Seriously considering to jump ship as well, because my MacBook Pro 2016 got BOTH a flexgate[0] screen and a swollen battery[1] on the same MacBook, and yet Apple refused to fix them for free, because they found a little corrosion on the logic board and concluded it as a "liquid damage". I was not given the option to fix the logic board only and get the rest free. Tried to dispute but there was no such channel (expect the general feedback form https://www.apple.com/feedback/macbookpro.html)...

It was a very frustrating experience in terms of the product quality, as well as the way they try to pick on customer's "fault" in order to cover the repair cost of their manufacturing defects.

Do this kind of Apple incidents happen more often than before? Coz recently I had a bad experience for my MacBook (to an extent that I wrote a blog post about it), which made me feel that Apple is getting less committed to its products and service level.
