If it's a mess then as a consumer they're doing a great job hiding it from me. I have 20 devices connected to my wifi and everything is running particularly smoothly. I did get frustrated at my 802.11n 4 years ago and dropped $250 for the best ac wifi router on the market and have had no complaints since then. Sure it could be more efficient from a technical standpoint but that's not something I'm interested in and I'm happy at how seamless things are for me right now.
