Just before LLMs became available to the general public, I worked for a small (fewer than ten employees) strategy consultancy. They had some industry-specific analysis tools that were in Excel, and my job was to turn them into a software product that customers could operate themselves. The owner had a mechanical engineering degree, but every time I asked him a technical question about the tools, he'd just give me a sales pitch for the thing I was trying to build for him. He was always pitching for new business, and seemed to struggle to get out of 'sales mode'. I have no doubt that if I were working for him now, he'd be pointing me to an LLM in response to any question.
