I didn't read the comment as such. Comment author assumes (correctly I'm sure) that some people reading feel like they aren't good enough to work at Google because they aren't hardcore software engineers. The point was you can still code and get the perks even if you aren't that, you just won't be on the self driving cars or customer facing projects.
The point I was trying to make is that you do not need to be at the absolute top-end of software engineers to apply for and work at Google.
If you are, then great! But if you are not the very best-of-the-best that is fine as there are still options for you to work at Google and write code for a living, just you probably wont be working on the sexiest world-changing products.
