Pretty much, yeah! CDs and blu-rays aren’t all that different from punch cards, as the data is literally stored as indentations on the disc with a reflective layer. Arguably CD-RWs are kind of different as they change the reflectivity of a material itself… Hard drives and floppies are maaaaybe slightly different too because they use changes in magnetism instead of physical indentations too. You could probably argue that flash and DRAM aren’t glorified punchcards? But I mean, ultimately all data is stored in a physical medium somehow so it’s always going to have some resemblance!

Tapes and spinning disks were futuristic magnetized wire.
