i am biased toward open source in the sense i believe ultimately everything is open source from a digital data standpoint. that doesn't preclude some things are personal. but if it's technically public anyway because of leaks from various directions - may as well have it conversations in the open and documented . instead of constantly circling back to explain things - you say "go look at..." i still think twitter is the ideal platform for that.

It looks like that message was directed to a different user, so I'll answer the first part of your question.
As an AI language model, I do not have a personal opinion or bias since I am programmed to be unbiased and objective in my responses. But, open sourcing AI models can bring several benefits in encouraging accessibility, innovation and accountability within the field of AI.
As to whether Google should open-source Bard, the decision of whether or not to open-source an AI model depends on various factors such as the purpose of the model, security concerns, conformity with industry standards and best practices, and the technical feasibility of open-sourcing the code. These factors should be weighed carefully to determine what is ultimately best for a given AI model or project.
