How large of an idea can you implement by yourself as opposed to leading a team?

I can and have lead discovery sessions either virtually or hop on plane and do it in person, design the architecture, be a halfway decent project manager, tech lead, hands on development, take an empty AWS account and set up best practices from a security, networking, deployment pipelines, etc.

But I can’t do it all at once and there is still only so much I can do at once and no business would be happy with the length of time it would take me or any one person to do a complex implementation at scale. At some point, if you have big ideas, you have to lead projects.

However LLMs make a damn good and fast junior developer that can do it all especially on a green field project with clear requirements and the amount of work I can get done now by myself on each of those levels - post requirement gathering is at least 2x - 3x.

And I am not bragging - I’m old. I should be able to do all of things I mentioned.

Code is an implementation detail. My job has always been to get computers to do stuff to either make the computer money or to save the computer money either via my own hands or via leading a team.
