Mapping AI's Evolutionary Tree: From the Perceptron and XOR to Transformers — and What Comes Next

abhishekkumar333 · reddit · 2026-10-17

The author maps AI architecture history as an evolutionary tree: early perceptrons failing at XOR, vanishing gradients spawning LSTMs, and attention-based Transformers becoming today's 'apex predator.' The deep dive includes a full timeline from 1958, foundational paper citations, and historical tweets marking each shift, and poses the open question of what post-Transformer paradigm could make self-attention look as primitive as an AND gate.
