Let’s be real. Having worked at $tech companies, I’m cynical and believe that AGI will basically be used for improving adtech and executing marketing campaigns.
It's good to envision what we'd actually use AGI for. Assuming it's a system you can give an objective to and it'll do whatever it needs to do to meet it, it's basically a super smart agent. So people and companies will employ it to do the tedious and labor intensive tasks they already do manually, in good old skeuomorphic ways. Like optimising advertising and marketing campaigns. And over time we'll explore more novel ways of using the super smart agent.
That's probably correct.
That said, the most obvious application is to drastically improve Siri. Any Apple fans know why that hasn't happened yet?
