No it isn't. You'd be surprised in the variety of people that you meet when you don't use algorithmic systems to do so. Just because you only maintain relationships with people who are not so glued to WhatsApp that they won't communicate through any other means, does not mean you have created a bubble for yourself.
They might do something when they get there and talk to people who are doing the same thing (or who just happen to be there).
I'm sure that is true. I was suggesting alternative ideas to calling random phone numbers as a means of getting out of one's "bubble".
It isn't. Nor did I say it was. The person I replied to said that not using WhatsApp is how social bubbles are formed. It isn't. That's what I was refuting.
It's true you are always able to avoid bubbles, and nothing I say precludes that ability.
However, information bubbles are a function of friction and defaults. If communication lessens with a people who don't share a particular view (ie, that Whatsapp has to be avoided) then that friction lessens exposure to that viewpoint, forming a bubble.
> you meet when you don't use algorithmic systems to do so.
AFAIK there is no algorithmic system on Whatsapp to meet people.
I'd also point out that this is exactly how bubbles occur. "Everyone I know hates WhatsApp/Facebook/whatever" says the person who refuses to communicate via those platforms.
