15. Video Store Clerk
    Renting VHS tapes and DVDs was a popular job before streaming platforms revolutionised how we consume media.

Mary Tamvakologos, Director of Operations at AnyBusiness.com.au, emphasised the rapid pace of change in the job market. "Most people assume the jobs around them will always exist because they are familiar. History shows that is rarely the case," she said. "Many of these careers were once considered stable, respectable professions. Entire training programmes, businesses and industries were built around them."

While some of these jobs disappeared gradually, others collapsed surprisingly quickly as new technologies became mainstream. The rise of streaming services, for instance, rapidly reduced demand for video rental stores. Search engines largely replaced printed encyclopedias, and smartphones effectively combined the functions of numerous standalone products into a single device.

Tamvakologos pointed out that the lesson is just as relevant for today’s business owners. "One of the biggest mistakes businesses make is assuming current customer behaviour is permanent," she noted. "The companies that survive major shifts are usually the ones paying attention to how consumer habits are changing before those changes become obvious."

She added, "Every business owner should occasionally ask themselves a simple question: if this business was launched for the first time today, would it look the same? If the answer is no, there is probably an opportunity hiding in that gap."

"History is full of examples of successful businesses that disappeared because they believed customers would always behave the way they did yesterday. The businesses that endure tend to be the ones willing to adapt before they are forced to," Tamvakologos concluded.

As society continues to evolve, so too will the professions that support it, leaving future generations with their own list of obsolete jobs to ponder.
