Is my summary inaccurate? The article is very careful not to extend any political slant to its data and findings, please extend me the same courtesy. (I'm not even American.)

TL;DR: DeJoy's changes appear to have made USPS slightly slower (0.1-0.5 days) in some places, but much less than the delta caused by a holiday like July 4th (see note buried at the very end).

The 737 is a far larger plane. The Celera has capacity for 6 passengers, while you can cram over 200 into a 737.

For a better comparison, the world's most popular aircraft, the four-seater Cessna 172, needs under 500 feet to take off in optimal conditions, although you might need 1500 feet if fully loaded and high up.

However, the Cessna Citation M2 business jet, which targets a similar market as the Celera, also requires ~3000 ft (again depending on weight, altitude, conditions). So not seeing a huge difference here.

The line to central Singapore has been closed, but there is still a pathetic shuttle service that crosses the causeway from Johor Bahru:

There are plans to replace this with a metro service and eventually build high-speed rail between Kuala Lumpur and Singapore, but both have been repeatedly bogged down by politics.

Once the Kunming-Singapore link opens, you'll be able to ride to rails to the southernmost point in continental Asia:

Despite the name it's actually a series of different routes, and while all of them still have gaps, the Boten-Vientiane link connecting China to Thailand (and hence Singapore) via Laos is scheduled to open in late 2021:

Although the corresponding line on the Chinese side also needs to open (ETA 2022):

9nGQluzmnq3M | 5 years ago | on: On the problems with automated contact tracing

I hate to rain on a good rant, but do you have any actual data to back up all these strong assertions?

Contact tracing (the old fashioned kind) works quite well when it's done aggressively and case counts are low. However, for most of the Western world neither is true, and throwing Bluetooth at the problem isn't going to help. Neither can it magically prevent infections from people who don't know they're contagious, which we've come to realize is a significant feature of how COVID spreads.

Running a telco is not that expensive. The problem is that building out the infrastructure in the first place is hugely expensive.

This is why most countries have only a few "real" operators that own and operate infra, and tons of virtual operators (MVNO) that run on top of others' gear.
