Apple's natural home is hardware, and the consume software integrated with that hardware. Off the top of my head I can't think of any "hard" software created by Apple, it's all about the UX and the integrations.

So unless Apple thinks it can outcompete it's BigTech competitors in something it historically hasn't done much of, best leave it to them.

This sounds like you’re either unfamiliar with what software they make or underestimate the complexity of things like a modern operating system. For example, most people would consider Swift hard, or the various Core frameworks, or things like designing a new modern file system and doing in place migrations on billion devices, etc.
