Is it time to change the design of the aircraft interior

Who is it that dreams up the design for the interior of an aircraft with trans Atlantic range.

Why has there been so little change in the basic layout since the Comet, 707 and the VC10

Clearly the designers are accountants who know how many bodies to squash into a cigar tube without inflicting injury but why has someone not figured out a better layout?

Look at the way passengers are configured and design the plane around them.

Passengers if you look come in singles couples or groups and into that category come families

So why not have family areas, why not have quite zones where the lights are dimmed and why not seats with laptop sized desks and dispense with the TV and games console?

Think of it babies and children who want to crawl around the ally ways could be in the bag where the duty free trolly and alcoholic drinks cart need not go
