I still see a place for a person who is capable of framing product relevance. These positions will transition to more resemble marketing and support positions than the traditional wheeling, dealing salesman.
I know it's not a popular opinion around here, but selling and supporting products The Right Way(TM) does take a level of creativity that computers probably will never possess.
Then again, after a technological singularity, anything's possible.
People who have more time then money are fine (or must) spend their time to duplicate the knowledge of others.
I would rather use the money that I have to solve problems because I have limited time.
I recently needed a firewall for a particular application. I would have loved to have had a 5 minute conversation with a knowledgeable salesperson who would say "this is the one that you want it's $895". Instead I spent what seemed like hours on the cisco site, the retailer sites and more and came to no conclusion.
And by the way anyone who thinks they can just "ask HN" or post a question doesn't understand that at the very least having someone who makes money off you and might have to take a return on a product if your unhappy is generally a better situation then anonymous internet advice. Advice depends on specifics and interaction which means taking the time to listen and reply to specifics of somebodies needs.
That said obviously there are salesmen who don't understand their product and are of no value.
For low ticket items, the questions now are "How do we capture more information beyond a simple search query?" and "How do we further promote product darwinism and eliminate the influence of advertising, marketing, salesmen and other product misrepresentatives?"
People forget that a lot of services are easily adaptable to new conditions. It sucked if all you knew how to do was to manufacture the perfect buggy whip. If you know how to sell something, it doesn't matter if it's cars or cattle or houses or industrial robots. Yeah, you have to learn about your product, but the basic skill set is quickly transferable.
If you're talking about sales that functions primarily as new customer intake and has no long-lasting relationship with the clients, like door-to-door sales, I can see a better argument for that going obsolete.
You're casting a pretty wide net there. Why don't you try to duplicate what I've learned since 1996 (about domains) or what took me years to learn in other businesses by just reading some internet "how to's" and articles.
Let's say for example tptacek is selling security services. Would it be wrong to rely on his years of expertise or try to roll my own solution. I would pay for that wouldn't you?
You start out by saying "virtually all middlemen who do not add significant value are obsolete". Then in the next sentence you say "this includes salesmen, sales reps".
By the way value is also defined in different ways. The beer distributor (who is actually required by some laws) is the middleman between the manufacturer and the retail level (bar or store). The purpose of the distributor is also to get the store to push their products over the competition. Therefore to the mfg. they do have value in the chain.
Large almost-monopoly molochs suck. Is it really the only way?
The market is competitive, but it's kind of monopolized by the big guys.
That's the main reason why flying coach is such crap.
So, you might think that removing 1/3rd of the seats and charging 33% more would be a revenue-neutral proposition, but it wouldn't be. Passengers who currently fly at the front of the plane would look at the cosier seats in the back and think "hey, actually -- I can live with that". Business-class passengers won't pay for seats at the front of the plane unless the seats in the back are sufficiently awful. Because the seats at the front of the plane are much higher-margin, the airline would lose money as a result.
(This isn't my own home-brewed conspiracy theory; this is based on reading Harvard Business School case studies. The things one learns whilst studying price discrimination theory during an MBA...)
This includes salesmen, sales representatives, dealers, warehousers (replaced by on-demand everything), many types of brokers, etc.
This is a huge chunk of the economy. In the old industrial economy there were layers and layers of bureaucracy and markups between the producer and the customer. Now there will be at most one. The customer and the producer will deal directly. Everyone else is cut out.
That one layer -- an Amazon type thing -- will be heavily monopolized by a few big players (Amazon, Wal-Mart, etc.) and will be very low margin / high-volume.
