It seems to be just that consumer tech doesn't evolve like it used to. It was insane how things went from the late nineteenth century to modern era, but lots of signs of slowing down.
While computer tech is going, it's now only doing so by scaling behind home electrical capacity. The high end server chips are just cranking the wattage because they can't improve within a more reasonable power envelope anymore. A 2026 laptop that replaced a 2020 laptop that was broken wasn't really significantly faster. In 2000, a new PC would have been more than 10 fold faster than a 6 year old PC.
Tech progresses, (e.g. just got a phone with a solid state battery that's crazy better than battery behavior before), it's just some of the biggest consumer electronics things are hitting physics and things we are used to advancing are just flattening out.

It's not that it won't improve, but it isn't going to cause a runaway "singularity" event.
Like the drama around the models "escaping" and "amazing hacks" have turned out to be something, but not nearly what people were afraid it was going to be.
A lot of the fundamental limitations have remained, and we are figuring out the scenarios where those limitations are fine or there is a way to create a feedback mechanism to try to reroll the AI until it passes. Lots of success there, but the fundamental disconnects are still there, just not important for the task at hand or can be worked around.
