I'm really curious how much valuations, especially for big companies, have been based on things like "anyone can create a website with no technical knowledge", "programming will just be natural language in a few years", and "you are now the manager for an infinite number of junior developers". I think wall street is a bit smarter than that, but I'm not totally sure. I'm thinking that there are expectations of efficiency gains across a really broad range of tasks, i.e. programming, support, copy-editing, graphic design, etc, which will lead to significant increases in economic value. But it's impossible to know what the broad market is thinking, so IDK
