Bitcoin is already in mass adoption but we want more of it because it's not yet the limit of it. When it's about Twitter and Elon, people are shouting for putting money where his mouth is and that's all about acceptance of Dogecoin.
That reply of Jack is a good one, there should be an exposure for lightning network so as bitcoin and that will certainly give another option for the payments.
If you haven't seen it, there's a followup:

It looks like Musk agreed to this deal.
IMO it won't be a big thing for the price but it's going to make more people aware of bitcoin. You bitcoiners might not believe it but there's still many people out there who use the Internet but know nothing about it.
Nice, this actually a good news if it's allowed. We just want to see the exposure of it and if it didn't click, hopefully Elon won't remove it and let it stay there for bitcoin's visibility to his users.
This is a good start, Elon is an amazing person who has a keen eye for the future world, Bitcoin is a very important part of the human process, this Twitter change I think it's giving Elon wings .
