I keep wondering why we can't have 2000s software on today's hardware. Maybe because browsers are de facto required to build apps?
The software is optimized for the machines used by developers. If you have latest MacBook pro max super ultra you are fine.
Contrary, I've been issued a virtual machine with 4 cores and no GPU. It takes 15 seconds for web app to render a table in the browser.
We could, but most of the 2000s developers are gone. Or, we no longer have developers left with 2000s attitudes and approaches to software development.
