We asked OpenAI's Dall-E imaging app to depict a bicycle.

Dall-e twisted handlebars

That OpenAI named its app Dall-E after eccentric artist Salvador Dalí, famous for his painting of melting clocks, amounts to a tacit confession. But when helping people repair and maintain bicycles, you want realism, not surrealism.

OpenAI's ChatGPT text generator went on its usual Internet bicycle-fishing expedition and found that our beloved Raleigh Twenty bicycle was sold with rear and front racks. ShelBroCo sacrilege!

This can't stand! Like it or not, human-AI partnership is key to a livable future. Robot shakes hands with humanAs of April 1, 2023, ShelBroCo is revising our business model to include review of AI-generated articles and imagery.

There is much work to do. We humbly offer assistance.
