Taycan is a complete validation of Tesla's business model circa 2013. I'm sure the interior will be very nice and it will handle well. Otherwise, it's technologically outdated. Some will buy it just because it's a Porsche, but there's only so many times you can go to that well.
You are talking two different groups of people. Tesla owners want to be able to tweet and text and do all sorts of other things besides driving while in their Tesla taxi whereas the Porsche owners care more about the handling and spirited driving of a Porsche. The only technology they want is a timer to tell them if they beat their last lap. They could care less about social media or having a huge screen so they can surf the web while the car is moving.
