Joining the amazig ShaderToy community, learning how to use SDF, and writing all my next ASIC circuit simulators in GLSL instead of Verilog since 2019 was the biggest "aha!" moment in my scalable parallel compute and 2D/3D UI career. Turns out, it's the bleeding edge I've started to use back then, 4 years ago, long before it becamr mainstream.
Interestingly enough, I missed the bleeding edge train of Attention, Transformers, LLM, GPT back then, but what I effectively was doin was thinking in parallel, and writing massively scalable GPGPU compute kernels aka CUDA or the bleeding-edge developments from Microsoft and OpenAI.
