What can you confidently say AI will not be able to do in 2029? What task can you declare, without hesitation, will not be possible for automatic hardware to accomplish?
Easy: doing something that humans don't already do and program it to do.
AI is incapable of any innovation. It accelerates human innovation, just like any other piece of software, but that's it. AI makes protein folding more efficient, but it can't ever come up with the concept of protein folding on its own. It's just software.
You simply cannot have general intelligence without self-driven innovation. Not improvement, innovation.
But if we look at much more simple concepts, 2029 is only 5 years (not even) away, so I'm pretty confident that anything that it cannot do right now it won't be able to do in 2029 either.
Success in not around any corner. It's pure insanity to even believe that AGI is possible, let alone close.
