AI image generators like Midjourney, DALL-E, and Stable Diffusion work through a process called diffusion. They start with pure noise (random pixels) and progressively denoise toward an image that matches the text description you provided.
During training, these models were shown millions of image-text pairs from the internet. The model learned the statistical relationship between textual descriptions and visual features. When you type "a Nigerian market at sunset, oil painting style," it uses those learned associations to guide the denoising process toward an image that statistically resembles what that phrase patterns in its training data.
The quality of your output depends heavily on your prompt. Effective image prompts include: subject description, art style (photography, oil painting, digital art), lighting description, camera angle, mood, and technical quality terms (sharp focus, 8K, detailed).
Midjourney is generally considered to produce the most aesthetically polished results and is easiest to use. DALL-E 3 (accessible through ChatGPT Plus) excels at following text instructions precisely. Stable Diffusion is open-source and free but requires more setup and prompt craft.

The ethical debates around AI are genuinely important and worth understanding. The key concerns:
Bias and discrimination: AI systems learn from historical data, which reflects historical biases. A loan approval AI trained on decades of lending data will encode racial and gender biases present in that data. A facial recognition system trained mostly on white faces performs worse on darker skin tones. These aren't hypothetical — they're documented in deployed systems.
Job displacement: AI automation disproportionately affects routine cognitive work — roles that offer stable middle-class employment in developing economies. The transition could be disruptive without policy intervention.
Privacy: AI systems require enormous data, raising questions about surveillance, data ownership, and consent. Generative AI was trained on copyrighted content without compensation to creators.
Misinformation: deepfakes and AI-generated content are making it harder to distinguish true from false, authentic from fabricated. This has significant implications for democracy and trust in institutions.
Alignment: as AI systems become more capable, ensuring they remain aligned with human values becomes more critical. The field of AI safety works on this problem.
None of these are reasons to avoid AI, but they're reasons to develop and deploy it thoughtfully.
