To celebrate the 100th episode of The Digital Human Aleks Krotoski explores how digital and analogue technologies make us think differently. And she'll do it by going 'old school' putting down the keyboard and mouse in favour of audio tape and razor blades. But this programme isn't about nostalgia, she'll be investigating the psychological experiences of using these different technologies. With the help of artists, musicians and photographers she asks if the endless possibilities we're offered by digital tools are as liberating as we think or paradoxically are they paralysing, making it impossible to choose one product, picture, tindr date over another? Are we more creative, and decisive when we're forced to be by constraints; as we used to be when camera's shot film with a limited number of shots and tippex was the only way to erase something we'd written? And are we too readily allowing our digital technologies to decide what's important. Whether in music or on the phone our digital devices strip out the 'noise'. Whether that's the background of where we're making a call, or the sound of fingertips on an instrument. When we lose some of that context what else are we sacrificing? Aleks will aim to find the right balance between the two domains, to make the most of each. Throughout the programme we'll also offer a glimpse behind the scenes of making a programme where the final assembly uses pre-digital techniques; and the scavenger hunt it required to find the long decommissioned tape machines and the people who remember how to operate them.
