Once you add the "s" editor (so you have a screen editor) and UUCP, v7 is an adequate daily driver, in my recent experience.  No, it didn't actually replace my Mac, but with a way to get data on and off it and a decent editor (which I personally do not feel "ed" is)...it's totally OK.  I can edit files and move them around, which honestly is most of my job.

How many of roughly 500 system calls (to say nothing of uncounted
ioctl's) do you think are necessary for writing those few crucial
capabilities that distinguish Linux from v7? There is
undeniably bloat, but only a sliver of it contributes to the
distinctive utility of today's systems.

Or consider this. Unix grew by about 39 system calls in its first
decade, but an average of 40
per decade ever since. Is this accelerated growth more symptomatic of
maturity or of cancer?
