Rapid prototyping with AI tools

The best use of AI for a solo developer is discarding bad ideas faster, not polishing good ones.

Key takeaway: The true value of rapid prototyping isn't getting to a finished product faster; it's getting to the 'fail state' of a bad idea before you've invested weeks of work into it.

The cost of curiosity

In solo development, curiosity is expensive. Wondering if a new grid mechanic would be fun often requires days of building the underlying logic, creating placeholder art, and designing a few test levels. If the idea turns out to be a dud, that time is lost. AI tools drastically reduce the cost of this curiosity.

Getting to playable faster

Using AI coding assistants to quickly scaffold the core logic of a mechanic, and AI art generators to mock up a quick visual representation, allows a developer to go from concept to a playable prototype in hours instead of days. The code might be messy, and the art might be inconsistent, but it serves its purpose: answering the question, 'Is this actually fun?'

The discipline of throwing things away

Because the prototype cost so little to make, it is emotionally much easier to throw it away if it doesn't work. This is the hidden superpower of AI in the prototyping phase: it encourages ruthlessness. You can test ten ideas, discard nine without regret, and focus your real, meticulous human effort entirely on the one idea that proved its worth.
