When we look at data scientists, there is a wide spectrum in their background, skillset, workflow, etc. When we look at the users of data science notebooks specifically, there are many people who don't want to deal with the hassle of running their own infrastructure (possibly even more than those who do). I agree with you that the ability to use your own servers is important for lots of use cases, but it's not a hard requirement for us to get the product out to the public and ask for feedback. So we don't have on prem or GPUs at the moment, but it's something that we are working on.
