My interest in Aldi goes back a long way... and the article does a good job of tracking the beginnings.. (very big in Europe) with a start in Germany by Theo and Karl Albrecht, who died in 2010 and 2014.
We first visited Aldi's in the early 1980's , soon after their intro into the US. Stores were pretty miserable back then, but inexpensive.
Currently more than 10,000 stores worldwide.
The US main office for the company is in Batavia Il, about five minutes from my son's home.
My fascination comes from an interest in retailing, and the efficiencies that have led to the successes of Amazon and Walmart. With the soon to be real, one hour home delivery, Aldi will be in the forefront of the soon to be huge Uber-like delivery phenomenon. (A whole new business by itself.)
The development of the industry, is a perfect example of a different type of Blockchain process, that we'll all be discussing in the near future. A step by step selection process that is continuously changing. (think a gigantic genealogy chart , but with ideas, rather than people)
While food isn't as glamorous as "tech", Aldi is the front edge of one piece of a world that will be moving in quantum leaps... in our own lifetime.
