Why it earned a slot
The recent JAX-to-GPU porting challenges with Gemma 4 reveal a growing tension in the AI hardware ecosystem. While frameworks like JAX promise write-once-run-anywhere flexibility, the reality of hardware-specific optimizations is creating new fragmentation. This isn't just about TPUs versus GPUs—it's exposing deeper architectural mismatches that will force practitioners to make hard choices between portability and performance.
