Excuse me, but how much time people have been developing the technology that powers ChatGPT. How much time and money has Google spent to create Transformers? How much time has been spent developing neural networks or CUDA devices. How much money has ChatGPT invested? Billions. GPT1 is from 2018, but neural networks have more than 70 years now. VR have more than 30 years since the early prototypes.
