TLDR: Fuel Efficiency.

If somebody actually develops supersonic private aircraft, we really need to start taxing aviation fuels. You could blow through your annual carbon budget in like an hour. Those costs need to be internalized.

I would be with you till I experienced South Korea.

Here in South Korea, there is institutionalized racism or something we call as institution enabled racism. People who are not Korean or white aren't even allowed in most clubs or jobs and it isn't illegal to do so.

Labeling deters bringing exclusionary views into tech projects, It could be just words, but I am happy to see the privileged society at least care for the minority in the west. I wish there was more of this in Korean tech websites, but xenophobia is so ingrained that people don't realise that it is wrong. People openly admit that they are xenophobic but don't see anything wrong with it.

In korea, labeling someone a nazi doesn't work as they don't care and can't relate. But the label that works here is calling someone "poor" or "ugly".

How many times better is a barrel jack?

Maybe they just need to flip it twice like inserting USB devices.

> Think about listening to a language unknown to you, one with different words, grammar and prosody. You will be at an utter loss to identify its words, let alone their meaning.

My experience learning French basically. I'd say understanding where one word ends and another starts was much easier for English and German. On paper I was able to grasp the rough meaning very quickly thanks to vocabulary shared with English and Latin, but listening took a year: I was facing a solid wall of sound, no cracks.

Funny! I am working on something similar for myself. But not restricted to just Gmail. I really want to clean up this mess in my accounts.

How did you go about the unsubscribe functionality? Also, I think I saw that Gmail has that feature themselves now.

No twist of fate, but self-sabotage in the form of being unwilling to use Lidar. Look how hard Waymo and Cruise are finding it to do robotaxis in a small geographical area and with Lidar. Tesla is trying to do robotaxis everywhere without using Lidar. They're solving a harder problem and are handicapping themselves while trying to do it.

Here's why Lidar makes sense. You want independent information streams that are cross checked. If both streams tells you there is no object in front of you, that's a way lower probability of being wrong than just one stream telling you that. You go from probability p to p^2 of being catastrophically wrong. It's the kind of probabilistic added safety of being in an aircraft that's capable of flying with only one engine. Even if one blows up with probability p, you're fine. You need a p^2 event for both engines to malfunction, assuming errors aren't correlated, which they probably are a bit, but not so much that the added benefit isn't massive.
