It might just be badly chosen example images, but the images in the article make a good case to me that even up to 64x64 bitmaps are superior. In the upscaled 32x32 computer icon the bitmap has a much better keyboard with defined keys, compared to the SVG and HVIF where it's a blurry mess. Similarly in the icon of the tape recorder the buttons (one of the key features of a tape recorder) are much more recognizable in the bitmaps from 16x16 up to 64x64 because the outlines are always a pixel wide, while in the vector they get lost in antialiasing on anything smaller than 128x128. Those might not be issues on more stylistic icons like many logos. The HN logo works fine as a single vector, same for the github icon or the wikipedia logo. But for more complex icons that depict real-world objects making vectors work over a range of scales is really hard
