ARM, RISC-V, and AI
Three questions on the ARM vs. RISC-V battle — what RISC-V actually has going for it in the AI era, why ARM is now making its own SoC, and where RISC-V still has ground to cover.

Why I Always Show Up at the Office
It is not just about separating work from life — it is about not missing the serendipitous collisions that only happen in person.
Computer Architecture Is Entering a Golden Era
AI-native workloads, edge fragmentation, and faster experimentation are pushing architecture back to the center of hardware value creation.
Semiconductor Development Cycles Will Shrink Faster Than Expected
As prototyping, validation, and silicon feedback loops shrink from months to days, chip development will start to move at a cadence much closer to software.
Using AI Well Starts with Redesigning the Workflow
Getting real leverage from AI requires more than adding a model to existing processes. It requires rethinking workflow design, sign-off cost, and the role of infrastructure.
