To me, this is the most damning evidence that our industry sucks at its job. We're so bad at making our products that users expect them to be slow and broken all the time.
Only if you are being amazingly reductive. VSCode is about changing desirable sequences of bytes into more desirable sequences of bytes, where the definition of "desirable" is stupendously complex and depends on state that exists on many other computers around the world. If you just want to change bytes you can open notepad or nano and watch as they boot instantly. VSCode is much closer to Eclipse than nano in its capabilities.

To me I think about things like screen refresh rate or keyboard latency. Some people demand 120hz or incredibly low keyboard latency. But I'd wager that the percentage of people who care about such things are a rounding error. Even among hardcore gaming enthusiasts, optimal fps has only doubled over the past three decades. So there is way more real time to do stuff, and developers fill that time! They might fill it with features or they might fill it with lower development costs.
What exactly can it do that Vim or Emacs can't? Vim starts up literally 100 times faster on my machine, with 17 active plugins. It also runs everything in a single thread and is still more responsive than VSC in almost all scenarios.
What are those stupendously complex features that somehow make a slow start unavoidable? Or to go with your comparison, why do you think Eclipse has a good reason to start so slowly, on a modern 8+ thread CPU and SSD?
Emacs I haven't tried nearly as much, but it has a poor Windows OS experience, and is also historically a "bloated" software ("Eight Megabytes and Constantly Swapping").
Of course there is no reason Vim couldn't be modified to do everything VSCode does but better, but until that happens VSCode will still have a place in my toolbox.
This annoys me as well. Visual Studio Code is about changing individual bytes in tiny plain text files. I don't think it has a single feature that didn't exist before. Yet its startup time is somehow closer to that of a full-fledged IDE, almost as long as the whole operating system needs to boot. Same with websites; a freshly configured email client can download a thousand messages from the server in a shorter period than it takes to load most news articles in the browser.
And the most baffling thing to me is that such things are so widely accepted. I've seen many users shrugging it off with a "that's just how computers are" mindset; many things are implemented so badly people don't even expect them to work properly.
This may sound a lot like "old man yells at cloud" material, but in the end it can't be denied performance is often at least an order of magnitude away from where it could be - my current laptop has 32 times as much RAM as my first PC, and it still swaps just as frequently.
