If you can't deliver features faster with AI assistance then you're either using it wrong or working on very specialized software that AI can't handle yet.
I've built a SaaS (with paying customers) in a month that would have taken me easily 6 months to build with this level of quality and features. AI wrote I'd say 99.9% of code. Without AI I wouldn't even have done this because it would have been too large of a task.
In addition, for my old product which is 5+ years old, AI now writes 95%+ of code for me. Now the programming itself takes a small percentage of my time, freeing me time for other tasks.
Quality is better both from a user and a code perspective.
From a user perspective I often implement a feature and then just throw it away no worries because I can reimplement it in an hour again based on my findings. No sunken cost. Also I can implement very small details that otherwise I'd have to backlog. This leads to a higher quality product for the user.
From a code standpoint I frequently do large refactors that also would never have been worth it by hand. I have a level of test coverage that would be infeasible for a one man show.
It's boring glorified CRUD for SMBs of a certain industry focused on compliance and workflows specific to my country. Think your typical inventory, ticketing, CRM + industry specific features.
Boring stuff from a programming standpoint but stuff that helps businesses so they pay for it.
