Round shank drill bits and three-jaw chucks are largely obsolete for job site use. Contractors are now predominantly using hex shank drill bits in an impact driver for conventional drilling, or SDS drill bits for masonry drilling.

Not sure if I agree here. Of course SDS has been the standard for quite a while in masonry uses, but impacts simply do not have the power of a full sized drill with a 1/2" chuck (or bigger) for more difficult materials. The 1/4" hex shank is pretty limiting for torque as well, and the chuck has far worse concentricity if you care at all about precision.
The hex shank bits are decent (although I'd say I prefer round shank with flats) but calling round shank obsolete seems a bit far.
