In hardware engineering this is called critical path.

Amdahl's law is common sense, but also the one of the reasons premature optimization is the root of all evil.

A small speedup on the longest (by time) part of the program is usually better than infinite speedup on a short part of the program.

The bottleneck is bandwidth and storage not computer power.

Data from sensor and to display are usually (but not always) raw and uncompressed.

To go beyond 8k 120fps we will need fiber, or better compression.

We have good codecs to move data online. And specialized ASIC to do live encoding with good quality.

The current compression defined by HDMI is very rudimentary.

Flow instability is one of the biggest challenges to get them to operate for long time without blowing up. Of course, there are others.

Any progress on the control of chaotic flow is great news. Even at subsonic speed.

Now we only need a consumer CPU from Intel with AVX-512 enabled.

I don't think Apple has interest in small markets. They are really good at making stuff at huge volumes.

Silicon on lunar regolith is mostly plagioclase, pyroxene, and olivine. Quartz (SiO2) is <1%.

Not exactly comparable.

The aviation industry is averse to change. Most planes are still being updated with floppy disk.

But I agree. High end commercial solid storage, such Optane, would likely exceeds the requirements needed by the aviation industry.

I wish the Sony protocol was open source. It is impossible for a hobbyist to work with SLVS-EC.
