What Next?

When mankind makes its toodle-oo,
thus closing down this human zoo,
I’m sure that there will be a sequel
that is more than mankind’s equal,
for in evolution’s quest,
nature goes from least to best.
Each form of life has not receded
from what form of life preceded.
When some great calculator reacts
to what’s been lost through human acts,
what difference will it make for gain
that will surpass the human brain?
And . . .
will music, poetry and art
vanish in that great restart?

The prompt words for today are quest, equal, toodle-oo, react,precede and calculator.
