Personally I say yes as our society becomes increasingly dependent upon technology, digital currency will become a more popular means of paying for different things and it is more effective and instant. I haven't used much physical money in the past 8 years and I rarely had any problems with that.
What do you guys think?

I don't think digital money will replace paper money. The use of digital money requires the Internet, and in some countries around the world, the Internet has not been widely used, which will limit the spread of digital money. I think the future of paper money and digital money will both exist, both of which are important forms of payment.
