This is not at all accurate when considering that internet access for one home is on average for 3 people, not 1, and internet is now used for work which requires video streaming and large file downloads.
That would be the situation I find myself in, and I can indeed have multiple people in the house on high quality, low latency video calls at the same time as large downloads from Steam and folk watching YouTube.
Maybe I'd get a faster download with a faster connection, but it's the low latency applications that are of top importance.
