Are sales spam emails going to start including personalized videos? I guess I'll look forward to the "Hello dollar sign firstname. I'm dollar sign agentname. My colleague recommended I connect with you, as you both work at dollar sign employer" template misfires.
I think that's one of those 'logical conclusion' things.
And it won't be emails. It will be the places where video is more appropriate: instagram, facebook, text message video, zoom calls.
