I don't know why, but it creeps me out. If it's that easy to test your body for "molecular" levels . How long before you are asked to be tested at your workplace, on interviews, etc.
It's already easy to test for political affiliation / religious beliefs as part of the interview process, but people aren't doing that. No reason to believe that something like this will be different.
The issue with political and religious beliefs is that they're generally irrelevant to your work but may be basis for discrimination. The chemical composition of your blood and other tissues may be relevant to your work but is generally not expected to be basis for discrimination.
This is why I think you counterpoint is not exactly spot-on. On the other hand I share your disagreement with Gattaca-inspired fear mongering: if chemical analysis of your tissues can provide useful information for recruitment we should embrace it. Interviewing is flawed and hard as it is, so any improvement should be welcome. My fear would be that chemical composition turns out completely useless like many other simplistic solutions to complex issues around selecting the right humans for any job.
>if chemical analysis of your tissues can provide useful information for recruitment we should embrace it.
I disagree.
There are no fields in which poor health is an advantage. So, that idea extrapolated, their are no jobs which wouldn't benefit in some way from having the most healthy staff possible.
I'm of the opinion that it is the job of recruitment staff to secure employees who are capable of doing the job that's asked of them, capable of advancement, and capable of a degree of amiability which will allow them to work well with the other parts of the system.
If chemical analysis were to be used normally in the course of recruitment, it'd no longer be a game of determining if the candidate was capable of the task, but rather a min-maxing of attributes which would be expected to produce a company with the results desired.
Simply put : I, too, fear that chemical composition is far too simple a criteria to judge a possible (human) candidate on.
