Their second milestone should show memory safety features, and AFAIK it comes up a year or two later.
These milestones will produce technology demonstrators - so there's no expectations people would be using Carbon for anything beyond small demos and maybe check if it can be integrated with their existing C++ codebases.
Then they will try to package up the language and tooling around it with these two flagship features. This is where they expect some people to use the language for real. The language will only support a subset of C++ (they haven't decided what exactly it should include), and they mentioned Rust-like subdivision into "unsafe" and "safe" Carbon. To me this all looks like even after those milestones it may take a while.
Also, while Google folks are hopeful they also donated billions to Rust to improve C++ interoperability there, too. They don't bet on one language only but rather see multiple of them develop and spread.
So, tldr: it's years and years away.
How does this work in other countries?
For a stable company that has a constant revenue stream and an established body of workers there's no much of a difference: instead of paying all tax for current year salary you pay 6 chunks of tax for 6 different years of salaries - which would be about the same amount.
For early companies things can be pretty tough. You may earn, say 100k in a year one and pay your employee 100k. Your company now has 0 in the bank, but for the taxation purposes the taxable amount is like (100k - 10% of 100k = 90k), at 20% corporate tax that would mean that the company has 0 in the bank but owes the government $18k in taxes. It's much harder to start a software business in this kind of environment.
H1B rules around changing jobs means that even if the employee joins at a market-level salary when they come to the US, they tent to stay at the same company much longer and can be exploited. The new company has to go through a lengthy paperwork process to allow the visa holder to switch jobs. Also, since the tech world tends to use things like stock options / RSUs / monetary bonuses for large parts of compensation package and those do not count towards "salary" you may have a situation where an h1b holder on paper seems to be paid fairly but in practice get only about 40-50% of what their peers get.
If they were allowed to change jobs freely they would be able to negotiate their compensation fairly. The companies would be less intensified to hire H1Bs to save money and would also consider local talent for same positions. Everybody would win: both H1B visa holders and their families and American workers, too. The only losers would be consulting firms (not a huge loss, to be honest, most of their employees are overseas anyway, so the can absorb the cost) and BigTech (they have enough money, anyway).
There are other problems for H1B holders, like getting a green card is something their employer, and not them, can do - another area for abuse. And then some nationalities have to wait much longer to go through this process then others (essentially, the US migration service says that the country has too many people from India and Pakistan already, thank you very much), and there are other issues I don't recall.
Still, there's no point comparing build costs between France and the UK as they're completely different cultures and jurisdictions. Instead, a more reasonable approach is to compare to recent similar project in the UK.
Edinburgh's tram covers 18.5 km and cost at least (they're still uncovering overruns years later) £1 BN. That's ~£50 MM or ~€60 MM per km. That's what CVLR should and will be benchmarked against.
VLRT seems gimmicky at first but the more I look at it the more sense it makes.
I haven’t found the projected figures for Coventry but it would be very, very awkward if they can’t beat the numbers above with a supposedly much cheaper track.

It is not: the post talks about the development progress of their web framework, which seems to be their take on server-rendered pages with islands of interactivity. Kinda like Astro or maybe like Remix.

As suggested by the OP, it approaches the problem from the angle of showing that e^x is the only function that is its own derivative.
There is also a follow up explainer giving intuition for e^ix as being about modeling rotations.

Then later we got introduction to e in terms of derivatives and complex numbers. However, compound interest was never used for exploration, and I only got introduced to the it’s connection to e and as an explanation for what e is late in my thirties.
How the mighty have fallen.
Meanwhile, every single real estate developer / agent sets their prices incredibly high hoping to sell or rent out the property to those mythical "wealthy expats". I saw a stat somewhere that less than 0.2% of all real estate transactions in the country each year involve foreigners, and yet everyone blames them for high real estate prices.
