I hold the theory that digital product designers are architects of the digital environment. Without claiming to be intrusive, I simply find a lot of common ground.
Both disciplines create spaces of use and consumption that propose experiences for users. In both cases a similar process is followed, it is essential to explore the project in depth beforehand; to know the needs of the users, the objectives of the product, the context of use, the location, the aspirations and needs of the client, etc.
A visual exploration is also done, references and inspiration are sought and a creative or design line is defined.
It is crucial to consider in the design phase how users interact with the product and how it will look and feel when using it. There are more experiential projects, and there are more functional ones.
In all cases, the project is limited to the framework of economic possibilities and time available. And in both disciplines, as could not be otherwise, the dilemma between design and art remains unresolved.
On the other hand, there are some fundamental differences.
It is seductive how architects are able to play with dimensions, lights, materials and shapes to design spaces. I envy the possibilities they have in the design of physical environments.

However, in digital products the interaction is more direct, the conversation between product and user is closer. And the great point: it can be molded and adapted to the use that users finally give it.
If an architectural project is wrong in the way it thinks it will be used, there is no turning back. But we, UX/UI designers, have the opportunity to do so, to evolve what we have created and accompany it throughout its life as a living, organic work that grows with its environment and adapts to it.
How wonderful.
In any case, this discipline, architecture, has at least 5.000 years of travel, so I suspect that we will have much to learn from it. And nothing more exciting than drinking from other branches, so I have asked my friends and friends architects and this is the recommendation of books that have suggested me to start (not everything is strictly architecture).

I share it with you, for those who may share this concern. I still haven't decided where to start... I'll let you know.
