For someone whose job is to inform the viewer, he failed despite having nearly 30 minutes to tell the viewer that their laptop can become a desktop without a dock! All it might need is a display adapter like HDMI-to-Displayport, but most modern monitors and laptops won't need anything!
Docks are cute but mostly unnecessary unless you plan to switch from desktop use to on-the-go use often enough to make it worth the extra cost, latency, and bandwidth/throughout issues with USB/ethernet/etc.
After the prosaic, needlessly long dock video, chock full of Linux and FOSS hate, I see him entirely in a different light. His videos are entirely scripted and honestly just filled with a lot of empty conversation. Sure, entertaining, something to watch - but really not very packed with knowledge. Sparse would be the right word.
