Dating app questionnaires have changed dramatically by 2030. Now immune and genetic status is just as obligatory as hair color or favorite music, if not more.
It all began after the now distant COVID-19 pandemic. Many online daters back then started to specify that they had been vaccinated or would be soon. The topic quickly snowballed. It's much easier to take the plunge and meet up in the flesh if you know that the likelihood of getting or passing on the infection is minimal. Moreover, having the same attitude to vaccination means the other person probably has a similar worldview.
COVID-19 is a thing of the past, but other infectious diseases are not. And the habit of checking a prospective partner's immunity to current ailments did not die. Gradually, this information migrated from the category of private confidential data to one's standard public profile.
Genetic tests underwent roughly the same evolution. Sure, there's no need to upload your entire DNA sequence for everyone to peruse. There is a generally accepted set of benchmarks believed to maximize the chances of a happy future together.
It doesn't stop there. The most progressive users already check mutual compatibility against a list of cybernetic body enhancements. However, many "naturals" do not like it when their partner's head emits a slight whirring sound from time to time.
