Muscle and Nerve: High and Low Voltage in Automotive E/E Architecture
High voltage is the car's muscle; low voltage is its nerve. Once compute centralizes and actuation goes by-wire, electricity stops being infrastructure for the E/E architecture and becomes part of the function itself. Power is a fourth plane alongside compute, network and software; a zonal architecture is only complete when power is zonal too; and distribution is not availability — autonomy needs not better supply, but energy that can still be proven after a fault.

A System of Operating Systems: E/E Architecture, the Vehicle OS and the AI-Defined Vehicle
The vehicle OS is not one operating system. It is a vehicle-wide software control plane — contract, orchestration and lifecycle — that governs a family of operating systems and only becomes engineering reality once the E/E architecture centralizes. E/E sets its boundary; it in turn redesigns the next E/E. Autonomy is its stress test, and AI thins its top while thickening its base.

Three ‘Threes’: Qualcomm’s 2026 Investor Day and a Collision of Architecture Taxonomies
A thousand-billion-dollar chip company independently reproduced the bones of a framework it had never heard of — and in doing so, showed that the fail-operational watershed is not a foundation but a through-bolt.

The Driver Exits: Why Autonomous Driving Will Change Everything for the Auto Industry
By mid-2026, autonomous driving has crossed its commercial tipping point. Removing the human driver forces the industry across the fail-operational watershed — turning the safety case into a first-order metric and rewriting the value function for OEMs, R&D disciplines, and the profit pool.
