An article in "Governing" about the potential for blockchain makes the classic pro-tech argument, with the class flaw. Blockchain is mostly associated with Bitcoin and other currencies with dubious reputations. But its really just a data storage system. There are many useful applications for blockchain, such as car titles. Imagine not having to wait for a title again. But, of course, the whole point of labor-saving technology is the elimination of the laborers.
Not to worry, the article says. These jobs will actually be replaced by better jobs. The example is that getting rid of 10 data entry clerks could lead to the hiring of 20 paralegals. The problem here is that a paralegal is a skilled, certified position. These are not the same, just as working at an Amazon warehouse is not the same as working at Gimbel's.
I fully understand creative destruction. I also understand that people can't just be swapped out like machinery. And many used-car buyers are going to be among the hardest hit.
