"I'm not saying we purposely introduced bugs or anything, but this is kind of a natural result of any complexities of software... that you can't fully test it"

In this quote by Will Wright, he highlights a fundamental challenge faced by software designers: the fundamental unpredictability and intricacy involved in creating software systems. Wright suggests that it is not the intent of designers to introduce bugs into a system, but rather, these bugs become a natural repercussion of handling complex software architectures.

The expression "I'm not stating we purposely presented bugs" suggests that while bugs are frequently an undesired outcome, they are not typically the outcome of negligence or malice on the designers' part. It acknowledges the messy reality of software advancement where regardless of best shots, defects can and do take place. This concept stresses the value of an iterative advancement process where feedback loops help in determining and repairing bugs.

The concept of "intricacies of software" reflects the complex nature of software application systems, where many parts, user interactions, and external elements can result in unexpected habits. As software application grows in size and complexity, it becomes progressively difficult to visualize every possible circumstance or interaction that might take place within the system.

When Wright discusses "you can't fully evaluate it", he is explaining an axiom in software application engineering: complete and extensive testing of every possible use case is practically impossible. This is because of restrictions such as time, resources, and the sheer variety of prospective interactions within a system. As a result, developers need to prioritize checking the most crucial and most likely usage cases, while acknowledging that some problems may just be found post-deployment.

Overall, Wright's quote underlines the importance of constant screening and adaptation in the software application development process, welcoming the uncertainty that includes complex systems, and recognizing that the presence of bugs is an expected part of the advancement journey rather than a conclusive failure.
