Nvidia's CUDA moat may not be as impenetrable as you think
Briefly

Nvidia's competitive edge rests heavily on its established CUDA ecosystem, which presents significant barriers for developers looking to transition to alternative GPU frameworks.
The deep-rooted CUDA moat complicates low-level programming migration, as specific hardware calls in CUDA have no direct equivalents in Intel or AMD systems.
Intel and AMD are actively addressing the CUDA moat, investing in tools like AMD's HIPIFY to ease translation of CUDA code to their platforms.
For developers deeply entrenched in CUDA, the transition to other frameworks can be daunting, requiring substantial code refactoring and optimization efforts.
