The most imminent threat to jobs that I can identify is drivers. Taxi's, trucks, delivery vehicles and buses.<p>We can see rapid improvement of self-driving technology. For sure, tech moves into mainstream more slowly than we generally imagine it will, but the sheer numbers of persons who could be displaced make even a relatively protracted implementation a big problem. Drive through Mountain View, Ca. on any given day and you'll see multiple Google autonomous vehicles. Uber, Apple, Tesla, GM, Volvo, .. most major auto companies, some minor companies and even non-auto companies are working on it with a high level of focus.<p>Two aspects of this movement may inhibit widespread deployment and slow the rate of robotic vehicles subsuming human jobs:<p>- The pace of legislation and the attending regulatory infrastructure. Governments are cooperating for the most part, likely attracted by the prospect of safer transportation in general. So I think this will not materially delay the roll out.<p>- The dilution of talent as these efforts compete for technologists may slow the progress of all of them, unless individual engineering leaders can attract and retain the top people.<p>The numbers look like this (2014), [1], [2], [3], [4]:<p>233,700 Taxi<p>665,000 Bus<p>1,797,700 Semi/Tractor-Trailer<p>1,330,000 Delivery<p>In 2014, that was roughly 4 million people who make a living driving. And the 2 most valuable companies in the world, Google and Apple, are working very hard to put these drivers out of work. What makes it particularly difficult is that these workers are typically uneducated and will have no place to go except minimum wage service jobs. Moreover, many former manufacturing workers took these driving jobs as a downgrade to income. And it looks like they have another target on their back.<p>Where do they go from here? Speaking for myself, I think the country has a moral obligation to make some accommodation and not just wave our hands a bit and say 'oh, they'll be fine'.<p>[1] <a href="http://www.bls.gov/ooh/transportation-and-material-moving/taxi-drivers-and-chauffeurs.htm" rel="nofollow">http://www.bls.gov/ooh/transportation-and-material-moving/ta...</a><p>[2] <a href="http://www.bls.gov/ooh/transportation-and-material-moving/bus-drivers.htm" rel="nofollow">http://www.bls.gov/ooh/transportation-and-material-moving/bu...</a><p>[3] <a href="http://www.bls.gov/ooh/transportation-and-material-moving/heavy-and-tractor-trailer-truck-drivers.htm" rel="nofollow">http://www.bls.gov/ooh/transportation-and-material-moving/he...</a><p>[4] <a href="http://www.bls.gov/ooh/transportation-and-material-moving/delivery-truck-drivers-and-driver-sales-workers.htm" rel="nofollow">http://www.bls.gov/ooh/transportation-and-material-moving/de...</a>
