Interesting post.I was getting my hair cut the other day and was dreaming of the day when a machine will cut hair. If the machines are really expensive - there might be room for the barber to sell time with them (like a tanning bed) - its more likely however that machines will be owned by everyone and hair stylists will have to find another lane.
This is true, no doubt since the introduction of robots in car assembly factories, many have lost their job.
