Just a matter of years. At&t will eventually be a pure wireless company. 5g, along with air-gig, will enable them to deliver gigabit speeds into even remote rural homes delivering everything. If a home or business has power, then air- gig and 5g can deliver. As their penetration increases, core decreases. Eventually it’ll get to the tipping point where they can easily sub out old core work. Or just sell that portion of the business off entirely. At&t won’t need to own all the plant it does now. Not even the backbone. They can sell it and lease it back as needed like many other companies do. This is Randall’s dream. To have a small a workforce as possible. Means more money in shareholder pockets.
Excellent point by @YDcLW4q-1boz.
