"We are worried that we would hit a dead-end and not be able to build what we set out to build." Listen attentively to your intuition. Your "worry" can stop you faster than any statistical or third opinion about whether AI is a hard problem. Doesn't mean you should stop worrying and continue. Spend time imagining your ideal solution in great detail --- touch, smell and taste it if you can. Judge based on how you feel about that end point. I heard someone said "AI is what hasn't been done yet." You don't need to prove your worthiness to anyone or any community by "solving a hard problem". Instead, as chasingsparks put it, "do what fascinates you".
