You didn't understand what he said at all and you are wrong. I ask you this... there are very different ethics and morals around the world, even many differences in ethics and morals between your home and your neighbors, so which ethics or morals should you have to be able to teach ethics and morals? The ones you have? lol
You can't compare Walmart to Amazon, Walmart is a northamerican thing, Amazon is global. Walmart has zero influence in the prices of the tomatoes grown in Europe.
Their international scale is similar, though I'm sure not in exactly the same places. Amazon had $118 billion in non-US revenue in the most recent fiscal year while Walmart had $101 billion.
If you limit it to only retail, Walmart probably comes out ahead.
Alas, them deciding to shut-down Book Depository means I can't purchase English/American books anymore free of customs-related taxes (I live in a Eastern European EU county), which makes me not purchasing those books at all (in many cases the taxes would end up doubling the purchase price, so it's not worth it). I'll never forgive Amazon for that.
Autonomous vehicles can use existing roads more efficiently. In fact, that's the whole point of this tunneling project. Think of a tunnel as just a stupidly expensive road and you'll see that simply having autonomous vehicles without the billions of dollars of infrastructure would achieve the same goal. Simply close a few roads for normal traffic and you have the same advantages but without the tunnels and power rails. Vastly cheaper. And there already are lots of roads. So, these vehicles could go to a lot of places instead of only a select few elevators above the tunnels.
And of course you could actually mix autonomous and regular traffic as autonomous vehicles get smarter. Like is already happening in parts of the world.
Also, the main issue in cities is not tunneling into a central location but distributing goods all over the city using e.g. cargo bikes, small vans, etc. Many of those are already electric and typically operate from distribution centers on the edge of the cities. Banning regular traffic out of the cities would free a lot of space for that. Some cities are already doing that or at least strongly discouraging car traffic. E.g. London, Paris, Amsterdam, etc. have large car free zones and lots of modern electric delivery vehicles.
The second condition is a bit stupid, most failures or inappropriate functioning of the system in software development can be considered a harm in economic interests...
> At the end of the day, you wind up in a lot of fairly pointless arguments about tech stack and coding conventions that 99.9% of the time don’t make a bit of difference to the final product.
99.9% of the time they do, maybe you don't see them functionally and visually, but probably you aren't measuring security flaws, performance and specially ease of maintenance which goes unnoticed most of the time...
