⚠ The Abstraction AssaultModerate threat

The central strategic threat to the CUDA moat is that the most powerful companies in computing have consciously decided to break it, and are pouring resources into the software layers that would make Nvidia's hardware interchangeable. Frameworks, compilers, and intermediate representations — Triton, XLA, MLIR, and the like¹ — are all, at bottom, attempts to let AI software run well on any chip, which would sever the coupling between the software the world uses and the hardware Nvidia sells.

This is a more serious danger than any single competitor, because it attacks the moat rather than the product. Nvidia can out-engineer any rival's chip; it cannot so easily prevent an industry from agreeing to abstract the chip away. And the motive is overwhelming: every large buyer and framework owner would profit enormously from a world where Nvidia's silicon competed on price alone, so the effort is funded by exactly the players with the deepest pockets.

The reasons for calm are that abstraction has been attempted for years and the performance tax has proven stubborn — running on any hardware and running best on any hardware remain different things, and Nvidia's privileged, early, deep co-design with the frameworks keeps its path the fastest. The abstraction layers lower the wall without yet leveling it, and Nvidia's cadence keeps rebuilding the height they chip away.

Moderate, and central — this is the thing to watch above all others on the software side, because it is the one line of attack the whole industry is aligned behind. It will not dissolve the moat soon, but it is a patient, well-funded, permanent pressure aimed at the exact seam where Nvidia is, in principle, most vulnerable.
