The standards of your industry and our culture were set a long time ago. So long ago that we often forget why… we forget and then we fail to change them.
In 1934, the rules of bike racing were changed to ban recumbent bicycles. And that rule has stood for more than 80 years, because Charles Mochet made the mistake of giving his faster, safer bike to a cyclist who wasn't respected. To preserve the status of existing riders who had paid their dues, the governing bodies banned the bike forever.
All of those riders are now dead, but the rule persists.
Cars have two headlights because horse-drawn carriages had two lanterns. Of course you couldn't put a lantern in the middle, that's where the horse goes. Now, it's easy to make a bar of light, one that illuminates from edge to edge.
And jobs used to be done by men, because statistically, it's easier to find people who can lift heavy objects among the males in the population. But now, most lifting isn't heavy, it requires insight and care instead.
What else is still stuck?
