How AI is changing software development: where it helps and where it falls short
AI tools dramatically speed up writing code – but do they speed up the right code? After a year of AI-assisted development, we share what works, where the limits are, and why architecture still belongs to humans.
2024 was a pivotal year for software development. GitHub Copilot, Claude, GPT-4 – AI assistants became part of developers' daily work. At Adaptine, we began using AI tools systematically, and after a year we have enough data and experience to say something more concrete than "it's a revolution" or "just hype."
In short: AI genuinely speeds up development. But not evenly, and not for everything. And for clients, this has specific implications.
What AI actually speeds up
The biggest gains come from work that is well-defined, repetitive, and where large amounts of examples exist in training data. In practice, that means:
- Boilerplate code – REST endpoints, CRUD operations, form validation, database migrations. Things a developer "knows how to write" but take time. AI does this in a fraction of the time.
- Unit tests – generating test cases is exactly the kind of work where AI excels. It covers edge cases a developer might not have thought of.
- Documentation – API descriptions, code comments, README files. Things developers put off. AI generates them continuously.
- UI prototyping – from text description or sketch to working component. Dramatically shortens iteration cycles in early project phases.
- Standard integrations – connecting to Stripe, Firebase, Twilio, OAuth providers. These patterns are well-documented, and AI knows them.
Our estimated speedup on well-defined projects: 30–40%. For a standard mobile app with a clear specification, backend and API, this means weeks, not days. For a clearly scoped piece (like a backend integration), savings can be even higher.
Where AI falls short (and why that's fine)
AI is a statistical model. It's good where patterns exist. Where no pattern exists – or where the key challenge is choosing the right pattern – AI is less helpful, and human judgment is irreplaceable.
Where we stay in charge:
- System architecture – which database model, how to design the API, where service boundaries go. AI suggests, senior developers decide.
- Domain expertise – healthcare regulation, security protocols, client-specific business logic. This knowledge must come from humans.
- UX decisions – what's the right flow for users? AI generates variants, UX designers evaluate them in context of real users.
- Security – code review from a security perspective. AI helps spot patterns, but responsibility for code security rests with the developer.
- Project management – what goes in v1, what to defer, how to set client expectations. AI won't do this.
What this means for price and quality
The direct consequence: for projects where AI helps most, we can offer a lower price or a shorter timeline. This isn't a trick – it reflects real savings in working time on mechanically intensive but intellectually repetitive parts of the project.
Output quality doesn't suffer. All AI-assisted code goes through standard code review. An added benefit is that AI-generated code tends to be more consistent in style and better commented than manually written code under time pressure.
One thing doesn't get cheaper: analysis and architecture. The time spent understanding your problem, designing the right structure, and making key decisions – here AI is not a substitute but a tool for faster idea validation.
Conclusion: transparency as a foundation
We use AI tools and say so publicly – because we believe transparency is the foundation of trust. If you have a project where AI-assisted development makes sense, we're happy to discuss it. And if it doesn't, we'll say that too.
