Maybe because --at the moment-- automatizing jobs is only profitable for very costly jobs, like those of traders. Or maybe because companies are worry of those "glitches" that we see in financial industry (like yesterday) where hundreds of billions may disappear in a fraction of second. Or maybe because it is easy to replace an employee that does not fit the job, but it is very difficult and costly to quickly find an alternative to a subpar automatized process costing hundred of millions.
