Your railroad question made me think... back in 1830s there was a huge need by both the public and industry for a railroad network. These days transport is a mess in some ways but it’s not a huge need for anyone. On the other hand the issues of what can we use smart phones for, what should social networks look like and how to advertise on these new mediums were actual problems of our day that companies and engineers had to solve. Hopefully we can move on to more interesting problems soon though.
