Boston never tanked. A team like Detroit in their prime never tanked. San Jose has not needed to tank. Tanking to get a team like Pittsburgh or Chicago would take a decade and still might not work (look at teams like Florida, Edmonton, etc.).
Tanking, even if it was a good idea, is not an option. Our only option is to acquire as much talent as possible at the best prices. Make trades that benefit a long-term state of mind. Operate our team like an efficient business, basically. We haven't done a great job of that but that's what we need to do.
