I have like wise experience except they didn’t feel pressure to learn and don’t feel attracted to it just like any other person.
Rock 'n roll became more attractive for a younger generation. The 1955 coup, ousting General Péron, led to a dark age in Argentina - and for tango. Whilst overall tango wasn't 'banned', as it was a ready cover for groups of men meeting where, under cover of dancing, they might plot against the regime. Curfews and limiting numbers gathering took a toll.
Interestingly minors were banned from AT clubs (so learning was difficult), but not applied to rock 'n roll. So, to meet a girl, you now went to a club where rock 'n roll was played; you didn't learn tango.
Then we have the long years of the repressive regime. Tango artists and performers joined the diaspora to Europe and the US.
1983 - the regime falls. People wanted, amongst other things, to dance AT again. But there had been no real tradition of teaching AT as we know it now. So it had to be re-learned, including the teaching.
We then start to get AT marketing, from Argentina as well. It's something you can sell, earn money, and promote the country's culture and image. 2009 it becomes a UNESCO Intangible Cultural Heritage.
So, in other countries, people start to add their own perceptions and emphasis to the culture of AT. Admittedly they have some 'heritage' from an earlier era, but there's also evolution through those times. Did those young people use cabeceo/mirada and sit at tables for rock 'n roll? Maybe so.
There wasn't a 'pressure to learn' - it was, in essence, 'banned' and there was greater attraction to rock 'n roll - where you could meet other people
