Builder The claim is about what the hardware does, and the philosophy is left open
Jyotiprakash Mishra posted The Dimensionality Gap: Three Scaling Barriers to AGI on Von Neumann Architectures, and a Path Forward Through Neuromorphic-Photonic Substrates on MDPI Preprints in March 2026 (DOI 10.20944/preprints202603.2196.v1). The argument bundles the von Neumann bottleneck, familiar from the memristor and neuromorphic literature, into a scaling claim about AGI, and names neuromorphic and photonic substrates as the alternative path.
The work is a preprint and this site reads it as a position paper, a research program rather than a demonstrated result. Its value for the substrate debate is structural. If cognition at general-intelligence scale hits walls that belong to the computing architecture itself, then the physical substrate is a first-order variable in what a system can become, which is the hardware-side version of the question this site tracks from the philosophy side.
This site covers the preprint in the dimensionality gap analysis. The Builder category refers to the proposed substrate path. The work makes no claim about consciousness.
