Awhile back, Canonical put out that they was not going to support 32 bit libraries. This sparked a outrage from the community. After a few days, Canonical put out that the 32 bit libraries will still be available just that they would be frozen. Pretty much things that require the libraries will still work.
Steam also made a comment that they are looking at other Linux distros to select which one will become the defacto distro of choice for Steam. This has got me to rethinking about switching from Ubuntu after 20.04. I just have to keep on eye on this issue carefully.
