For pre-encoded HDR 1080p Google (youtube) recommends 15Mbps target rate for the video and 0.5Mbps for the audio (5.1). For 4K the numbers go up to as high as 85 and 0.5.
I use a rough rule of thumb that 'livestramed' things at the same quality should be double those bit-rates as a maximum.
This gives:
FHD 16Mb/s
4K 86Mb/s
I'd say it's reasonable for a 'single household' to have a number of guests over, say if they're having a party or if relatives are visiting for the holidays. Lets call the peak use 12 guests.
86 * 12 ~= 1032 Mb/s ; Thus Gigabit is NOT overkill. It is capacity and freedom for a small family and some guests to enjoy content and/or collaboration without anyone 'hogging' the connection.
It's not uncommon to have 4-6 simultaneous streams in a household. Two children with a TV and a tablet each, and the parents watching a movie. And they need to be able to game/browse at the same time.
It may not be what the majority to, but it's a non trivial part of the population.
4-6 simultaneous streams of what? Browsing and gaming require little bandwidth on a sustained basis. 4K is the only thing that makes a dent in modern broadband connections, and it's not like people can watch more than one of those at a time even if they have multiple devices capable of doing so.
We're a "cord cutter" household with three adults and a four year-old who has her own iPad. I wouldn't be surprised if we were top 1% for bandwidth users. Tops for us is probably one 4K stream (25 mbps), 2 HD stream (5 mbps), and then trivial amounts on top of that from the three adults intermittently playing on their phones. I've got 150/150 now, and will be upgrading to 750/750 when Verizon rolls it out in Annapolis. But really only because I can, not because I can use it.
Teenagers stream some series to the TV, watch a twitch on the tablet and game. I kid you not, this seems to be a normal usecase for some teenagers. Thats potentially a 4k and 1080p stream. Have two of those in the house and parents that want to watch a movie. That is, with your numbers of todays streaming, 85mbit, so a 100mbit connection will have very little room for improvement.
And improvements are coming, 4k 60fps HDR streams will come sooner rather than later, and they consume upwards of 100mbit pr stream.
The fact that you had to concoct such an absurd scenario to get 1Gbps of throughput kind of hammers home just how far we are from having a real use for such speed.
