We don’t have to move everything to the computer. Also that doesn’t mean the existing models and solutions don’t already fit.
There are many things which benefit from being digital, which aren't digitized enough. Usually this means third parties are making a lot of money by offering a platform until digitization happens.
If you sell any product or service to the public, these are generally the steps you go through to benefit from digitization:
1. No digital presence at all.
2. Digital presence through a third party which takes a 15%-25% cut of sales.
3. Digital presence through a SaaS which has a monthly fee.
4. Digital presence which you own yourself.
Step 3 and 4 are still very underserved markets, where customers could make massive savings or sales increase. And those who offer these solutions will profit.

Do you also understand that most people fucking hate to use computers? The only reason normal people use computers so much and even have their entire careers in front of computers is that those machines can perform tasks extremely efficiently.
In French a computer is called "an organizer". In Swedish it's called a "data machine". And with the Internet, it's also a communicator.
If you run a business, would you like to compute everything in your head and organize all your things in filing cabinets and have all your data on papers everywhere?
