Thank you for the interesting question and for sharing your experience! I have similar approaches to working with AI.
I completely agree with the limitations of using AI with personal data and in matters related to legal or regulatory responsibility - these areas require a very careful and professional approach, and AI does not yet replace experts there.
For me, AI is a great assistant in routine tasks, such as editing and improving texts, writing drafts of letters or documents, helping with formulas and code. It is especially convenient to use AI for generating ideas and speeding up work with information.
The idea of internal Q&A via custom GPT sounds very promising - this can significantly increase the efficiency of access to the necessary information within the team.
In general, I try to use AI as a tool for supporting and speeding up work, and not as a final source of decisions, especially in critical issues. Thank you for raising such an important topic!
