Coaxial cable connections in the US have such meager upload bandwidth that cable ISPs do not even bother advertising or specifying a minimum upload bandwidth.
Download being 300Mpbs but upload 20Mbps IS kind of irritating though.
When did 100Mbps become popular for home LANs even?
Also, smartphone proliferation made streaming from home NAS very convenient, as well as home security cameras and smart home features.
I disagree that current upload capacities are adequate. With 1Gbps+ upload connections standard, we might actually see privacy forward solutions that do not require us to depend on cloud services.
I'm pretty sure new PCs and laptops have had gigabit standard for probably about 10 years.
Enthusiast and prosumer motherboards are now coming with 2.5 gigabit networking.
