My daughter says that about me too.
Newest MBPs are definitely not AX. Are there really any mainstream brand laptops being sold with AX wifi? Just last month I bought my wife a loaded 2020 XPS13, and AX was not an option.
Many "nicer" Windows based PCs have 802.11ax cards now. Certainly my Thinkpad does, and I see several options on Best Buy's web site. But not yet as common as 802.11ac.
