What drives technological advancement?

Five factors drive technological advancement: profit, efficiency, convenience, safety, well-being, and curiosity.


Profit is a major force behind innovation for three reasons.

Firstly, organizations seek innovations to improve the quality of their product or service. Superior quality makes the product more appealing to the consumer, which helps the business stay competitive. For instance, a bank offering a comprehensive online platform and smartphone app may draw more customers who prefer to handle all their finances online without in-person visits.

Secondly, businesses turn to new technologies to rapidly scale up production. For example, automation has allowed factories to increase their output, and thus generate greater profits for their owners.

Moreover, this same technology usually helps businesses expedite processes to reduce labor hours. A factory that relies on automation not only produces more than one relying on manual labor but also reduces labor costs for the owner.


The need for efficiency that drives technological innovations transcends mere profits in business. New tech makes everyday life and tasks more productive for all of us by letting us get more things done in less time. In turn, this efficiency frees up more leisure time.

For example, a Roomba vacuum cleaner eliminates your need to vacuum your home by yourself, while a dishwasher takes care of your dirty plates with minimal human input. So, instead of spending an hour on each of these chores, you’re free to go about tasks machines cannot yet accomplish, such as decluttering the house and organizing your things. Thanks to just two of these machines and the tasks they automate, you can save a good two hours when cleaning your home.

The need for efficiency that propels tech goes beyond home chores – we also innovate to optimize our leisure time.
