For me if Elon Musk didn't tweet about it people would just ignore it.
I think it gotten that high because of his followers not just in crypto but also his non-cryptocurrency followers bought it.
He got a massive amount of followers not just on crypto currency so maybe those non crypto people also bought Doge because of his words.
The community will not ignore it because dogecoin is also a close friend of bitcoin, it also has a certain reputation and use purpose, users will still care and invest, dogecoin will also have the usual pumps every year, this scenario runs through each year and very little changes. This year received even more luck when the value of dogecoin started to work and immediately Elon Musk gave enthusiastic support, such a spike is more staggering than every year but this also creates mixed opinions and has a significant effect on the reputation of dogecoin
