Transformer dominance is partly explained by hardware synergy: eliminating sequential recurrence enables massive parallelism, which GPUs — the dominant ML training hardware — are specifically designed to exploit.

Justifications

SL — Transformer parallelism and GPU dominance form a mutually reinforcing advantage

Antecedents (all must be IN):

IN transformer-no-recurrence-enables-parallelism — Transformers eliminate sequential recurrence found in RNNs/LSTMs, enabling significantly more parallelism and shorter training times.
IN ml-gpu-displaced-cpu-2019 — By 2019, GPUs displaced CPUs as the primary training hardware for large-scale commercial cloud AI

Dependents

These beliefs depend on this one:

IN hardware-architecture-coevolution-drives-progress — Hardware-architecture co-evolution has been a major driver of ML progress: compute scaling was a primary driver of the deep learning revolution, and transformer dominance is partly explained by GPU-parallelism synergy — suggesting future breakthroughs may benefit from similar hardware-architecture alignment.
IN transformer-flexibility-plus-hardware-enabled-rapid-speciation — Transformer dominance stems from a unique combination of architectural flexibility and hardware synergy — the unified attention mechanism enabled rapid speciation into encoder-only (BERT) and decoder-only (GPT) variants within one year of the original paper, while GPU-friendly parallelism eliminated the compute bottleneck that constrained all RNN-based predecessors.
OUT transformer-ideal-scalable-architecture — The Transformer is the ideal scalable ML architecture — unified attention enables flexible specialization across tasks (encoder-only, decoder-only, encoder-decoder) while GPU-friendly parallelism ensures training efficiency scales with hardware investment.
