>But when it comes down to spending millions of dollars to set up emergency electronic systems in hospitals, to take over certain human tasks, so the staff can't be seen as working (can't be sure of the details but I saw it on a docu. re. Israel years ago), at the risk of patients, it gets a bit "unnecessary". :-)

FWIW, one of the absolute rules is that you can ignore Sabbath prohibitions in order to save a life. So much hospital work is not prohibited on the Sabbath at all.
