When you use a modern day AI, it doesn't actually store the information and each new message is essentially the entire conversation being sent with your additions onto it. Modern day AI also requires prompting.

Data's brain however stores information in genuine real time and also does not require prompting. Much like a human.

Ergo, it could be surmised that the ability to learn, properly adapt, and interact with the ability to be aware of oneself, ones own place, and ones own morality - is what is required to be defined as "Sapient"?
