Depends on distance and size, there is a lovely chart. My projector at 10 feet away is night and day difference at 4k. Mathematically 8k should look identical, so I haven’t spent the money to try it to confirm.

The 1080p thing is true in the age of 40” TVs but not so much now, think Costco has a 95” TV if not 100”.

> it's widely accepted that there isn't much benefit for most people above 1080p

Is it? By whom? For larger TVs, closer distance, or a combination of the two, there absolutely is value from 4k. https://i.rtings.com/images/optimal-viewing-distance-televis...

Though I'm unlikely to ever upgrade from 1440p on my computer, personally.

It depends on TV size. If you've ever experienced Netflix on a 75" TV, 1080p content looks mediocre on it. So really it's better expressed as "there isn't much benefit for most TV sizes."

Yeah, but that's based on a hard limits, the physics of the eye. The example was poorly chosen.

> Your example also counters your point: A lot of people do not care about 4k, and even less do care about 8k or above. We reached a point where most people are completely happy with the quality they get.

And when (not if) we get to the 4k (or 8k) equivalent of LLMs, they'll just be baked into hardware and we'll have near instant responses while running locally.

There is no future where OpenAI, Anthropic, etc survive with their current business model; at some point we will hit a point where training a new model is done only every 5 years or so, and in that scenario we aren't going to be running models of pricey server GPUs with latencies measured in seconds and full responses measured in minutes.

We'll be running locally with sub-millisecond latencies and responses measured in milliseconds. There is no way for any big company to compete with the current business plan of selling inference or subscriptions.

I dare say many are watching on handheld devices and not big screens. At least a sizeable percentage I would say. My guess.

Likely constrained by the fact people are mostly watching low bitrate Netflix streams.

I'd argue we've already hit the ceiling. Can you truly tell the different between SOTA models from 9 months ago and those from today? There are some improvements but they're mostly marginal.

Plus there is a chance the actual scaling that matters is beyond our reach. Think instead of TB models, PB or ZB models. We don't even have that kind of information. Humanity in its entire history hasn't generated 1ZB of information.

There's barely any media in 8k. There's so many ppi you can squeeze before your eye can't tell the difference anymore.
