Let’s assume that in 10 years, AI has advanced absurdly, insanely fast, and is now capable of doing everything a Senior SWE can do. It can program in 15 different languages, 95% accuracy with almost no mistakes, can create entire applications in minutes, and no more engineers or SWEs are needed… What will all the devs do? Do they just become homeless? Transition to medical field, nursing? Become tradespeople like plumbers, HVAC?
You seem like someone who hasn’t really worked in software development.
Software engineering does not simply mean coding. A production grade software application goes through analysis, design, implementation (where coding happens), testing (several phases), release and maintenance. Not to mention infrastructure concerns (storage, databases, microservices, service orchestration, middleware, etc). The whole process is too nuanced and complex to conclude that AI would make the whole career obsolete. It might shake up some areas of software engineering but only a small part of it.
You’ll still need people to verify that the AI generated application actually behaves as per the business logic, runs optimally with the hardware you have and scales as your business grows. Which means engineers for testing and reviewing the generated code plus engineers to setup the infrastructure where the application will run.
