The digital economy is such a big industry and I've read some quotes in the past that if a business is not on the internet, soon, they'll be out of business.
No, that's not entirely true. There are cities where people aren't technically advanced or the highest percentage of the population is 30-40+ and have no idea how things work online. If in this particular city, you create an online shop or a website, that will be a waste of time and resources because everyone is old-fashioned. The Internet needs businesses that are in capitals and in advanced cities, like Barcelona, Madrid, Berlin, Munich, Milan, Dublin, Oslo and etc.
