I agree there are no signs of it going away. But speaking on the merits, it would be better to have one standard, and DisplayPort has so far taken the edge on capability and interoperability. HDMI is a redundant player kept in place moreso by convention than practicality.
In addition to leading the charge on bandwidth, DisplayPort has historically supported passive HDMI conversion (DP++) as an extension of the standard, while the same has not generally been the case for HDMI to DP. This situation has evolved somewhat over time, but not to the extent that we need to continue developing two parallel standards.
I am calling for an industry-wide shift to DisplayPort, with passthrough HDMI support for as long as we need, not just the port's removal from laptops specifically.
