I found it interesting. Being an older person in a long term relationship with someone I met in high school, the online dating stuff seems much harder for a lot of reasons.
Firstly, meet someone when you are young they are more likely to be of a similar socio-economic group and share a lot of values by default.
Second (and I realise this is controversial) if you fall in love when you are young and stupid, the pair of you will become adults together and that shared experience will get you through shit that would turn your hair white.
I thought the article provided some insight into how you are supposed to replace the older model of dating when the tech side of things offers too much pressure to do things quickly i.e. assess and cast off, or move straight to sex in a week.
So to me it seemed like an assessment of things you should consider to slow things down, be honest with yourself and prospective partners. Not overthinking, properly thinking.
