What people in history do you believe would have utilised the internet for the greater purpose,if they had access to that technology at the time?

Would it have changed the course of history in any way,or would history be more or less untouched had we been online maybe up to a century ago?Whose “work” would have benefitted most by this, whose would have perhaps caused a greater danger or threat.Purely hypothetical question of course, just interested in any opinions given.
