I do agree. But what I am trying to say is that we should be pushing for 6K and 8K ultra wide monitors rather than the old hack of 2 monitors to one computer.

There are times I actually prefer 2 separate monitors. Allowing one monitor to quickly go full screen while continuing to use the other monitor is quite useful in my workflows.

Virtual desktops are also more useful with two separate displays, or at least lend themselves to different use cases.

it's not a hack though. i prefer 2x4k. i hate the curve (no straight lines) and UW is too wide to be comfortable (eye and neck angle). 2x4k, one straight on and one angled is ideal. i spent 2 weeks and spent $8000 on monitors to test this out. 34UW at normal desk distance is perfect, however 2x4k is better overall. I actually use 3, as I use the macbook screen as the 3rd.

that said, i have no issue with your choice. for some applications (eg video editing is the default choice for ads of UW monitors) it is really better.

i do have issue with you denigrating 2 monitors. it is not at all "an old hack".

Out of curiosity, when did you last use a single monitor instead of your current dual monitor setup?

I’ve been using an ultrawide since 2015 but have almost always had a second side monitor with it. The period where I didn’t have a second monitor was short as having a separate monitor has always come in handy. All of the extra space on an ultrawide is great but when you’re doing something that takes the whole screen, it still leaves you in the same position you would be with a single 16:9 display.

Not the GP, and I really don't agree with their position, but I did switch from two monitors to a single UW last year.

TBF my old setup was a decade old so it was merely a 24" (1920x1200) and a 19" (1280x1024 in portrait).

Though my new display has a much larger logical size, the inability to put something fullscreen on one of the monitors (whether the small one or the large one, depending on the content) is definitely one of the drawbacks I had a hard time getting used to, not only can it be inconvenient, it actually wastes space as I can't get rid of window decorations, which putting e.g. a video player or browser window in fullscreen allowed.
