Unlike text-based AI that relies on descriptive prompts, some advanced design tools for physical components work in reverse. The user defines 'no-go' zones and constraints, and the AI then generates numerous optimized design possibilities within those boundaries.
Implementing AI is becoming less of a technical challenge and more of a human one. The key difficulties are in managing change, helping people adapt to new workflows, and overcoming resistance, making skills like design thinking and lean startup crucial for success.
To optimize AI costs in development, use powerful, expensive models for creative and strategic tasks like architecture and research. Once a solid plan is established, delegate the step-by-step code execution to less powerful, more affordable models that excel at following instructions.
AI assistants empower engineers to tackle tasks outside their core expertise, expanding their capabilities from a single deep specialty ('T-shaped') to multiple areas of depth. This allows for more versatile, self-sufficient team members who can manage broader responsibilities.
Creating user manuals is a time-consuming, low-value task. A more efficient alternative is to build an AI chatbot that users can interact with. This bot can be trained on source engineering documents, code, and design specs to provide direct answers without an intermediate manual.
'Vibe coding' describes using AI to generate code for tasks outside one's expertise. While it accelerates development and enables non-specialists, it relies on a 'vibe' that the code is correct, potentially introducing subtle bugs or bad practices that an expert would spot.
The future of AI is hard to predict because increasing a model's scale often produces 'emergent properties'—new capabilities that were not designed or anticipated. This means even experts are often surprised by what new, larger models can do, making the development path non-linear.
Judging an AI's capability by its base model alone is misleading. Its effectiveness is significantly amplified by surrounding tooling and frameworks, like developer environments. A good tool harness can make a decent model outperform a superior model that lacks such support.
Don't blindly trust AI. The correct mental model is to view it as a super-smart intern fresh out of school. It has vast knowledge but no real-world experience, so its work requires constant verification, code reviews, and a human-in-the-loop process to catch errors.
