Space Data Centers May Tackle Inference First

This interview discusses the possibility of placing data centers in space. The interviewee is more optimistic than expected, highlighting a few key takeaways:

Cooling issues are solvable, and costs might even be lower than terrestrial data centers.
Single-chip failures aren't a major hurdle: System-level redundancy can absorb the fault instead of relying on chip replacement.
The true uncertainty lies in whether the failure probability can be pushed low enough at the entire data-center level.
They believe small, inference-only space data centers could emerge by the early 2030s.
However, space data centers capable of supporting frontier training are unlikely within this timeframe.

Overall, space data centers will likely start with small-scale inference scenarios rather than immediately handling large model training.
