From a Single Neuron to Transformers: Mapping AI's Evolutionary Tree and What Comes Next

abhishekkumar333 · reddit · 2026-10-17

The author maps AI architecture history as an evolutionary tree: from perceptrons mimicking a single biological neuron and the XOR problem, through early networks and vanishing gradients that birthed LSTMs, to attention-powered Transformers that 'ate the world' — each roadblock forcing a paradigm-shifting mutation. The deep dive includes a full timeline, foundational paper citations, and historical tweets, posing the open question: if Transformers are AI's apex predator, what does the post-Transformer era look like?
