If it takes 60-80hrs/wk, then you need a better workplace regardless of nature of communication. Unless you plan to live like monk (meaning no family no friends out of work) - beware tho, monks have pretty much guaranteed membership for life you do not.
Yes, my observation is the same - the people who spend 60-80hrs at work do take all their socialization into workplace. Meaning they waste time of people who want to work at work and then go home - either because of kids or because of aging relative or because of anything else including hobbies.
The above is one more reason to avoid fun cultural workplaces. They tend to want all of you, not just your work.
