That graph places software engineers in the top-right quadrant, suggesting that they are predictable and "grammatical". However, I believe there should be a distinction between writing code and engineering. I would not classify software engineering as entirely predictable. For instance, while you could use a script to handle emojis with ChatGPT's help, it would be challenging to use the same strategy for a solution involving large systems that have multiple failure points and span multiple regions. Moreover, even if such a system were successful, multiple redundancies would need to be in place to prevent large-scale disruptions caused by downstream failures.
On the other hand, the chart places executives and investors on the 'safer' side. However, I think that with the real-time information available to AI, investing as a 'job' could be at a higher risk of being replaced. The same could be true for many executive positions (assuming that we are comparing merit-based positions to those based on nepotism).
