Bringing modern compute, edge AI, and hard-tech investing into orbit

Guest: Edward Ge – Founder & CEO, Aether

Most spacecraft still fly computers comparable to late-1990s desktops while our phones race ahead with Moore’s Law. In this episode, Edward Ge explains how Aethero is building radiation-tolerant, long-life computing for space and enabling distributed AI at the edge in orbit. We also dig into why hard tech rarely “goes to zero,” and how space + defense will shape the next generation of infrastructure and talent.

Topics

• Why space missions still run on decades-old processors and what must change
• Building reliable, radiation-tolerant compute and distributed systems for multi-year space missions
• Hard-tech fundraising, human capital, and defense as the launch customer for orbital compute

Takeaways

• Modern compute in space is constrained by reliability and radiation, not just performance and power.
• Hard-tech investments compound via infrastructure and talent, even when individual startups fail.
• Real orbital data centers will likely emerge from defense-driven, distributed edge compute in space.
