I feel compelled to quote the late great Sean Lock:
"I'm incredibly organised. Like for example, if I make tea, I don't make one cup of tea - I'll make a big batch of tea and then I'll have a cup of tea and then I'll freeze the rest of it. And then when I want to have a cup of tea, I'll just break off a bit of frozen tea. Put it in a pan. 25 minutes later I've got a lovely cup of tea without all the all the hassle."
I assumed because the category was "things that aren't actually real chips / potato fries" - by being real pieces of fried potato these are disqualified 😅
I guess my point is that it isn't a particularly important part of the design of Wi-Fi - they included it in the very first iteration in 1997 and realised by 1999 they didn't need it. Therefore Wi-Fi would likely have been born regardless of the invention; Bluetooth would not.
I was surprised by the choice of 'Mother of Wi-Fi' though - Wi-Fi hasn't used 'frequency hopping' as such since 802.11b was released back in 1999 - so very few people will have ever used frequency-hopping Wi-Fi.
GPS only uses it in some extreme cases I think, but I'm not an expert.
However, Bluetooth absolutely does depend on it to function in most situations, so 'Mother of Bluetooth' might have been more appropriate.
