It's Official, Polygon Is Full Of Crap!

From the latest PlayStation blog post by Thomas Grip:

Sometimes an attack will barely make a scratch, sometimes it will knock you down and force you to crawl out of danger, and other times you will die on the first hit.

Also, for clarification:

Finally, they explain how there really is no way to die in SOMA, but rather; "The game takes the player closer and closer to a more disturbing state of being".

They never said that there is no way to die in SOMA. This is the exact quote from the Polygon article you used as source:

Frictional is also experimenting with "a fate worse than death" in its next game, SOMA, in which the "basic idea is that 'death' is not final but takes the player closer and closer to a very disturbing state of being."
