Maybe. It sort of depends on how renewables shake out.
I could see DC gaining in popularity because you don't have to invest the hardware to convert renewables to AC for transmission. But at the same time, IDK, The AC grid works just fine so I have a hard time envisioning replacing the whole grid with a DC grid. Just doesn't seem like there'd be enough gains.
I do think intergrid connections will be more common. Micro/macro grids might also be more popular. Perhaps we start seeing subdivisions with their own grid/battery backups to improve reliability and allow the overall grid to disconnect them temporarily under load?
