The Last

I work in hydroponics and
I am the very last.
There was a time not long ago
When 50,000 souls or so
Were living here, no longer though,
That time has surely passed.

On this wheel spun deep in space,
The wheel of time turns true.
They aged, they got new hips, new hearts,
Replacing all their worn out parts,
Technology's unending arts
Constructing them anew.

Until they were reduced at last
To just their human brains.
And then the cyber brain arrived,
Their consciousness and thoughts revived
Inside a processor contrived
So nothing real remains.

I work in hydroponics and
I am the very last,
The last that's wrought of flesh and bone,
Of DNA and chromosome,
I'm hurtling through the Great Unknown,
A relic of the past.

But yet, somehow, the time rolls on
Exactly as it should.
The truth is that eternity
Is shrouded in obscurity,
For everything that couldn't be,
There's something else that could.
