Major difference in my mind: - an engineer, given a problem, invents and tries multiple solutions and stops when the solution is good enough. The goal is product innovation and shipping. - a scientist

Can't agree more. After trying out ChatGPT 5.4/5.5 for two months I feel it's far from replacing human researchers, even though it's enabling me to do things not possible before. The effect on how out
