Ownership that can be exercised
Portable files, intelligible architecture, and explicit relationships reduce the cost of changing tools. Ownership is more than retaining a login: can a builder export the content, understand the model, and recover from a service failure?
A tradeoff, not isolation
Managed services may create excellent leverage. Evaluate their portability, operational burden, and exit costs rather than rejecting them automatically. AI assistance should increase the builder’s ability to understand and maintain the result, not create a system only its generator can explain.
