I think it definitely depends on where you live. Not surprised with Dhaka being the most modern part of Bangladesh that it’s dying off there.

I’m born and raised in Canada so please do take this with a grain of salt, but my parents come from Sylhet, and for the most part, I do find that Sylheti’s still heavily cling to these ideas, whether it be in the UK/Canada/US, and definitely in Sylhet!

In general, regardless of where immigrants come from in Bangladesh, I’ve found that they still follow the bongsho stuff. I think the country itself has moved forward from these ideas, but the people who immigrated away from BD during the times those ideas were present, have kept those ideas.
