I was (somewhat obliquely) quoting Arthur C. Clarke from 1969. It's been 56 years, and in that time the present system has yet to come close to destroying itself.
We might be able to say it hasn't destroyed itself yet?
And what is meant by the "present system" is unclear. Plus the present system cannot be the past system so your choice of words is kinda weird!
Sorry, pedantic nitpicking can be a hobby. I don't like this comment.
