I do believe that time keeping, computers, and other technology are overused and overly relied on. (There is also damaging other stuff due to these technology, which is another issue. There are other issues too; these are clearly not the only thing.) They have their uses, but should not be excessive at the expense of anything else. If they fail, then you won't do unless you know and have not destroyed the older possibility, and if they do not fail, then you may be trapped by them. You should not need to know what time it is to sit down to eat, or to wake up and to sleep, etc.
