Do you think in the not-so-distant future, the "Mail Man" will become obsolete as all mail will be delivered electronically?

I was out for my daily walk in my neighborhood, and the mail man happened to be doing his rounds, and I was watching him and it got me thinking, with today's digital age, couldn't things like bills, payments, coupons, ads, subpoenas, just be sent out electronically? They could reach you within in a matter of seconds, rather then a matter of days. Of course this is assuming everyone in the country had access to a device and internet. If I'm not mistaken, Finland and Estonia have gone 100% digital, or if it's not 100%, it's pretty darn close.

I know physical items would need to be sent out physically. But something like bills could just be sent out digitally. It would also solve the problem of people who go abroad for several months, not being able to receive or pay their bills.

I'm not saying it will happened in our generation, but do you think a time will ever come where all paper mail, at least in developed countries will become digital?
