This idea seems to be coming up in multiple places.

Here's one from Deepmind:

Many years ago (13?), I was around when Amazon moved SABLE from RAM to SSDs. A whole rack came from a single batch, and something like 128 disks went out at once.

I was an intern but everyone seemed very stressed.

I should update the post with details.

I ended up using DFRobot firebeetle because it respects sleep mode. I'm at 15 months on one charge with a 10Ah battery.

Shameless self promotion: I wrote one of the more cited papers in the field [0], back in 2016.

A key challenge: very few labs have enough data.

Something I view as a key insight: a lot of labs are doing absurdly labor intensive exploratory synthesis without clear hypotheses guiding their work. One of our more useful tasks turned out to be interactively helping scientists refine their experiments before running them.

Another was helping scientists develop hypotheses for _why_ reactions were occuring, because they hadn't been able to build principled models that predicted which properties were predictive of reaction formation.

Going all the way to synthesis is nice, but there's a lot of lower hanging fruit involved in making scientists more effective.

At Amazon I set up an evaluation approach based on whether the system completed the desired task (in that context it was "did the search result using the speech recognition return the same set of items to buy as the transcript.)
