As big as a giant, powerful and clever in mind;
Not liked by many, I was hard to find;
Evolving small in size, lickety-split I emerge;
Befriended overtime, having me is the urge.
Transforming life, I am earth-shattering;
Never tired, no qualms when catering;
The more I am told, the more I do things;
I sing and speak, and needs no bathing;
No legs no arms, and not any feelings.
This riddle is diddle; reading it is half the battle;
B@loopuu was the first to figure out; leave a comment on your way out.
THE ANSWER: C . O . M . P . U . T . E . R.
