How did the previous generation live like this

I was talking to an uncle today about my AM experience and quickly realized that it was a mistake. He’s an extremely practical person and doesn’t really believe in vibe check in the AM process (I regretted even mentioning this). For context he mentioned he chose my aunt after looking at photos and talking for just 1 hour during the meeting. He mentioned he got all the answers he needed in that 1 hour to make a decision. He was asking me why I am taking so long to talk and take a decision, when it’s supposed to be so simple and straightforward. I obviously couldn’t level with him and didn’t even share the details of some reasons why I rejected some matches (basically red flags that previous generation people won’t understand).

Which made me wonder how did the previous generation people get their answer after just looking at photos and talking once. I am not talking about dating where you will spend a lot of time with general vibe checks and go with the flow. In general the guy and girl will have different opinions on various things and have different expectations and unless you discuss them you cannot figure out compatibility (not exactly vibe check but more of a discussion on expectations). Doesn’t have to take a very long time, but will definitely take more than one meeting. It’s a life decision that you definitely cannot take on a whim. Did the concept of compatibility not exist in the previous generations? Or did people not know better and just accept their fate and not question anything?
