Personally, I think the future is in messenger apps. Why login to Instagram or Facebook to see updates when you can have a family/friends group in Whatsapp/Telegram/Signal (pick your poison).
To be fair people were saying the same thing 20 years ago when AIM, ICQ, MSN Messenger and Yahoo messenger were the big thing. All messaging platforms will eventually die is my experience thus far.
That's generous.
Also, it’s worth noting that HN isn’t exactly representative of the population at large.
