What I understand as "ultimate workstation" would be a smartphone that once connected by usb-C to a monitor, becomes your computer.
Then, you don't need any other device, hence "ultimate".
Convergence, Samsung Dex, lots have tried but nothing mature yet. Well, Dex is mature but closed-source and Samsung-dependent. On the linux no-android smartphone side of things, hardware is too low-cost and the phone aspects of linux too brittle.
Aurora is just a new distro...
Android 16 is adding "Desktop Mode" to do exactly this, I bet in a few Android releases this will be good enough for most "desktop usecases". They'll have a "Linux" app that gives you a VM exactly like WSL2 on Windows or Crostini on ChromeOS.
If we allow ourselves to dream it's not impossible we'll be able to run Windows games on Android in some future :)
