Time?

Clocks no longer tick or tock;
Clocks no longer chime.
Clocks no longer run, or not,
Dependent on the wind.
Clocks; no longer fast or slow
With gears that break or bind.
Clocks no longer bragging of
The "jewels" that you can't find!
Clocks no longer clocks, but NOW
Computers with a brain --
Besides the time, they tell you
If in weight, you lose or gain!
