One way to use AI to speed up your projects:

Let your Support/QA/Sales engineers use AI to create features / fix bugs. They're closer to the customer than your developers are.

Even if what they deliver is complete AI slop and has to be rewritten, that pull request is a far better specification of what customers actually want than the ticket you used to get.

Too bad you fired all your QA/support engineers a few years ago.

In most organizations, critical path time and effort spent on coding is probably 10-20% of overall time. Overall software development effort for a software development project is probably ~50% total, and if you're lucky half of that is coding, so if coding is now 1.5x to 5x as productive, then we'd expect software projects to take up to ~40% less overall time and regular project to be ~3-8% shorter for the same output...

This is why I have been replacing my product owner and product manager with AI. For the life of them they have no clue about their product that I am building. AI is giving me far better problem definitions based on my observations on best practises and customer input than any PO ever did.
