maybe! I video conferenced on 1.5up for a week and I did have to turn down send quality, but other than that, it was fine.
I think the bigger issue is that if you can only get 1.5 in 2020, then that means that the physical layer between you and the internet is tenuous. Like, DSL far away from the DSLAM and thus packet loss and line noise.
I worked from home for years on a 2mps symmetric link from a wireless ISP in Tanzania, video conferencing worked well enough (Google Hangouts or whatever it was called 5 years ago).
For the heavy uploads I usually resorted to doing the upload from a VPS instead though, when possible (build the artifacts from that VPS, so that both the build and upload are much faster).
