Brick-and-mortar stores are doomed. I can only see a few types of products remaining in brick-and-mortars: Clothes that you want to try for size, fruits and vegetables that you want to sample, and restaurants... any others?
The need to sample things by taste (or other senses) could also conceivably end in the near future through downloads of software packages consisting of instructions for chemical synthesis of tastes and appropriate output settings for the sensory simulation hardware. [1]
