The problem with investors is that they've been oversold on the "AI" part, and are expecting magic robots that will replace humans in a few years. Remember, the key motivation for investing in AI or ML is to become a more competitive business, by reducing (or eliminating) human labor costs. That's it. Luckily, ML has become very incorporated in the modern workforce, but mostly as part of specific tools that can eliminate easy and tedious tasks - just as intended. So yeah, it's sad that the big investor bucks have to come from more "exciting" projects, because there's a vast landscape of problems that can be aided my ML, even though they're not as exciting as self-driving cars, robot doctors, or whatever - and don't require some monstrous deep learning model to be solved.
