Yeah that's the big problem. The Internet (e-commerce, specifically) is an obviously good idea. Technologies which facilitate it are profitable because they participate in an ecosystem which is self sustaining. Brick and mortar businesses have something to gain by investing in an online presence. As far as I can tell, there's nothing similar with AI. The speech to text technology in my phone that I'm using right now to write this post is cool but it's not a killer app in the same way that an online shopping cart is.
