We spend 20% of our time coding because compréhension and communication takes up the other 80%.
The same applies to most jobs in fact. If AI can make a Latte, are barista out of work? They spend 20% on the machine because of bureaucracy ? The hello sir, how's your day been are ceremonies. Much needed ceremonies even though nobody cares and say "fine thank you".
Since the premise is flawed it's hard to make an argument about the future of engineers.
