And you have not considered to enter offline-first, the service worker API has to load? Again, Grab has been doing this for 12 years. PWA is not new and they have chosen native apps.

But most of us did not assume to know better than Grab unlike you.

You do know that Louisville is THE major distribution hub for UPS in the US, right? Even if the UPS warehouses were not already built decades ago, it seems to be pure common sense that UPS would build warehouses to hold cargo . . . for their cargo hub.

Probably because in 12 years of developing iOS applications, developing PWAs does not meet their needs. Bear in mind, Grab is spend lots of money for their infrastructure. If PWAs was the best option, they would have chosen it.

Why are you assuming Grab is still using 12 year old technology? They are developing iOS which means tablets and phones. I seriously doubt anyone is still using 12 year old phones or tablets to use Grab apps.

Maybe you should do some research. I would venture the #1 reason PWAs are not used is they require a constant internet connection. In the case of Grab that means depending on reliability of Malaysia's mobile networks. While Malaysia does not have the worst score in the world compared to the likes of Pakistan, it is the worst in the region. A native app would only need internet to connect periodically whereas PWAs would never really work.

Let's summarize: You still don't know why a computer with 12 years of experience is doing something. But you're sure you know better. Again, have you presented your ideas to Grab?

With a decent SSD and a decent CPU. I would not put it past some companies to still be running with CPUs that barely pass minimum requirements and using the slowest HDDs.

Considering that Grab has building iOS apps for over 12 years instead of developing PWAs, I would guess they know more about their business than you. Have you presented your ideas to Grab?

1) Commercial pilots have to be certified to fly models of aircraft. No rules say pilots can only certify on one type of aircraft for their entire career. Some pilots certify on multiple ones. 2) UPS and FedEx fly more than the MD-11 as mentioned in the summary that it was a small part of their fleet.

1. Wresting was on TV long before video games. 2. Brothers and cousins were hitting each other slingshots and rocks long before TV was invented. 3. Your anecdotal evidence does not "discount" everyone else. It only reflects your ego that you think that it does.

Yes because wrestling never existed before video games. . . oh wait it did.

Like many things in the cloud, the flexibility was probably they could add/remove more machines easily with no long term commitment. The problem with cloud has always been at some point, the cost of leasing is greater than building on premises as the number of machines/data/bandwidth reached a certain threshold.

.

Only if saving money was the only goal and nothing else. In this case, not being able to develop iOS apps using Windows or Linux is a significant obstacle over any cost savings.

Then you haven't been paying attention. Since the Mac Mini launched many, many companies have used them as servers. The main reason is they offer high performance per watt in a small package. The demand is high enough that companies offer custom racks for Mac Minis for higher density in cabinets.

And why is it a questionable decision? Currently, the M series chips are the best in performance per watt and can beat Ryzen chips in some benchmarks. For Grab, since they need Macs for iOS development, what alternative do you propose?

If you read the story, the main reason they are going away from a cloud based solution was cost. As the number of Macs increased over 200, they found that buying their own hardware was cheaper. The major change for Grab is they own the Mac hardware now instead of renting it.

Due to demand, companies have designed racks to hold lots of Mac Minis in server room cabinets.

In this story, Grab is replacing 200 Mac Mini servers they are renting on the cloud with 200+ Mac Mini servers they have on premsises:

Obviously Grab does not think Mac Mini servers as "the worst idea ever".

Maybe you should read the histories of 19th century real life Gangs of New York

The Bible has depicted violence for millenia. The Iliad by Homer. Books by depict violence since the 1700s. It appears that basis of your arguments is recency bias.
