Xpath is still used for e2e tests and things like scraping. Especially when there aren't better selectors available.
Windows 11 has full spectre/meltdown mitigations by default. That Wikipedia article doesn't mention Windows 11 at all.
It's 5 mg/kg (or 15 mg/kg due to faster metabolism) for rats, and 25 mg (not per kg!) for humans. To be clear, 25 mg is a completely normal dosage that has been used in previous human studies.
The article is somewhat unclear about the rationale behind the dosages, whereas the paper itself provides a better explanation:

"The rationale for dosing regimen utilized was based on a number of factors. First, we sought to model high-dose used in a clinical study for chronic pain, where patients were administered a psychedelic dose (25mg) of psilocybin. Using the standard allometric scaling method, a human dose of 25 mg of psilocybin translates to a mouse dose of 5.14 mg/kg; this informed our starting point for dosing. However, mice exhibit a significantly faster metabolic profile for psilocybin compared to humans, leading to a shorter half-life and more rapid systemic clearance of psilocin; the elimination half-life of psilocin is ~0.9 h in mice vs 1.8–3 h in humans. Due to this rapid clearance in mice, a higher dose of 15 mg/kg was selected to ensure sufficient systemic exposure comparable to those observed in human clinical trials."

Lots of low-quality construction work though. Anecdotally, I used to live in a 30-story building in one of the special economic zones. My building had horrendously large cracks in the concrete, and even though I knew rationally that it wouldn't come down, it didn't feel safe, especially during typhoons, etc.

The prices depend on the city, apartments in Chongqing cost around $1,000 USD per m², about 1/5th of the prices in cities like Beijing and Shanghai.
They asked users of the VPN service to install a certificate, that's how they did it.
