I mean if you've built 7 side projects (and we assume it's the same phase since total time from idea to shipped product barely decreased), how are these things still a bottleneck to you? I'm assuming you're building in a domain/language you're comfortable with by now (unless you're crazy and try something fundamentally different on each of those shipped products).
Why will the 8th project still have those things as the bottleneck given your experience?
Also if you're not seeing any real gains in productivity, why are you using AI for your side projects and wasting tokens/money?
I use AI for side projects because Google gives me a stupid large number of tokens that refresh every 6-24 hours on my existing $10/mo Google One plan. I see it as my civic duty to help increase their costs by producing slop that I generally throw away anyways because it doesn't actually work after it gets generated.
At work, I was told to use AI but it doesn't actually work for anything that I couldn't have handed off to a brand new undergraduate intern. So I use it for things that I don't care about then go spend twice as long rewriting what it output because it made the task longer by being wrong.
