If you're primarily interested in the science and engineering content, nebula is a wonderful platform where membership fees directly support content creators.
one way to look at it is a blessing in disguise. instead of dissociating with YT, now you have all this time to figure out who you actually are and then become that thing. i imagine it's more rewarding than passively watching YT.
figuring out who you are isn't specifically career related. it's whoever you are. the focus here is doing/being authentic. authenticity isn't a passive activity.
