A lot of people here work with text all day every day and we would rather work with text that looks like it came out of a laser printer than out of a fax machine.
One person talks about a laptop, another talks about their big coding desktop monitor, a third talks about a TV they use. None agree how much 1080p clarity makes sense for usage because the only thing quoted is resolution. This drives the assumption everyone is talking about the same sizes and viewing distances based on the resolution, which is almost never the case (before the conversation even gets to the age old debate of how much clarity is enough).
I'm sure if you ask the original commenter, they don't mean 1080p looks great for reading books at 34" just as much as GP wouldn't mean to compare screens of different sizes either.
As others said, resolution is not everything. DPI and panel quality matters a lot.
A good lower resolution panel is better than a lower quality larger panel. Uniformity, backlight color, color rendering quality, DPI... all of them matters.

For some reason people then blame their old displays rather than apple for this.
I sometimes connect the same 24" monitor (an ASUS VZ249Q) to my M1 MacBook via USB to DP (so no intermediate electronics), and the display quality feels inferior to KDE, for example.
Same monitor allows for unlimited working for hours without eye fatigue when driven from my Linux machine. I have written countless lines of code and LaTeX documents on that panel. It rivals the comfort of my HP EliteDisplay.
The first part is obvious, for the second part if you're looking at slides and docs during the whole meeting, getting a super high fidelity view of all the other participants also looking (probably) at the slides doesn't help in any way.
I mean, Google Meet has a spotlight view exactly for this reason.
