CXL can drastically change ratio of memory to CPU and potentially even drive down demand for latest memory gens (mixing different gens of memory via CXL). Could be an interesting shift to think in terms of designing and building large scale data storage and retrieval systems at low latency.

You don't need a microcontroller to build a realtime system, it could work equally well on an ARM or RISC-V machine. Determinism is key, not feature set; however, you will want to avoid modern features such as dynamic frequency scaling or the x86 system management mode that operate outside of the control of the operating system.
fair, I left out what I really wanted to say. The simplicity of a microcontroller means it's hard to shoot yourself in the foot when building realtime systems.

Why are 8bit microcontrollers still a thing?
In addition to low power and unparalleled reliability, the microcontroller make it possible to build a realtime system.

Smart glasses + Video + AI => What's the social score of the person I am looking at?
I wonder who in audience was cheering for Horizon Worlds getting more features. There are hardly any useful experiences in there. Mostly it's obscenity screaming people, alarmingly often sounding very young.

I found "dumping/serializing state" greatly helped me.
I got into a habit of writing down things that required continued work next day, at the end of my workday. Initially I started doing this because it would take too long to get back into the depth needed to be productive especially after a long weekend or context switching for a day or two due to something time critical. The most effective form of "state dump" being specifically what is the next thing I need to immediately work on given next opportunity.
Overtime I realized, this "checkpoint" allowed me naturally to evaluate how much time and energy I spent on something and be specific about the next thing that would move me towards the outcome I wanted. This focus would:
1/ put my mind at ease, because I know what's important was written down and I don't need to spend mental energy keeping the state alive in my mind.
2/ It would direct my thinking towards what is important to do next time around rather than thinking of interesting but nuanced thing that are actually low value in grand scheme of things.
3/ Often, narrowing down what's the next thing I need to do meant I had a solution next morning and would often experience high productivity in first few hours of the day.
ymmv.
What's the value add when comparing this with `atop`? atop has a history recording feature that I have relied on in past.
