A touch-screen fridge? A seven-blade razor? Why is everything suddenly so complicated? | Adrian Chiles

Modern technology is supposed to make our world better. But my flat's lighting system' is broken, and I long for a single, simple light switch

I started shaving, tackling the wispiest of bumfluff, 40 years ago. I did so in an attempt to stimulate growth in order to make me look older, so I would have a better chance of getting served in pubs. Not one of these three things came to pass. The razor I used had two blades. I remember thinking how that felt excessive for my needs; one would have done. This was 1983 - 11 years after, according to its website, Gillette came up with the Trac II(R), the first twin-blade shaving system". And it was a good 15 years before Gillette was breaking the performance barrier with the MACH3(R), the first three-blade technology, for an even smoother, closer shave".

The blade arms race was on, providing a rich source of comic material for, among others, Billy Connolly, I recall, and Mitchell and Webb. But on the razor makers ploughed regardless, breaking new ground with ever more blades. Gillette, with a fine flourish, skipped four blades and went straight to five in 2006. And at five it has stuck, instead coming up with other stuff to keep our excitement high, most recently a heated razor that delivers instant warmth in less than one second at the push of a button and provides a noticeably more comfortable shave". Reassuringly, though, the blade race continues apace with the Dorco Pace 7, World's First and Only Seven Blade Razor". Seven!
