Interesting because by then codebases might have become so complex that these can no longer be modified, maintained nor understood by humans, so replacing AI with HI (human intelligence) will simply no longer possible.
That then represents a certain vendor lock-in or Mafia stand off: either keeping paying or have all the code go up in smoke.
Certainly not everyone will be facing this dilemma, but it certainly isn’t sci-fi considering the track-record of big tech.
Or perhaps AGI is reached and suddenly AI solves this all by itself.
It's also confusing that the term AI has become synonymous with LLMs as it covers other things like text prediction/correction.
So AI can be a tool or a service depending on how you are using it and what you are using it for.
