For my job, I use Copilot, which is built on GPT-4, and I have zero concern that it’s going to replace me.
It’s very useful, don’t get me wrong. It makes generating new code in applications that already exist a breeze a lot of the time (minus hallucinations and other forms of mistakes, of course). But it simply can’t create whole new applications of any complexity from scratch, and requires actual developers to check the code it does create. It doesn’t actually know what you want, it’s just auto-completing based on what its model decides you want.
Again, it’s very good at that. But it’s not so good that you can replace a team of developers with just one… Or worse yet, with an MBA who thinks he can figure it out without paying anyone.
