It’s interesting because there is a view that we already have this. You can deploy most of the infrastructure you need to do the kind of thing the author is talking about using a few hundred lines of docker-compose.yml. The author alludes to some of that - grafana, postgres, etc.

What is missing is the glue, or the business logic, or maybe just the custom frontend you can charge a lot of money for ;)

Using any blogging software and stripe or square or paypal you can setup an online store that comes close to the experience that shopify offers - to the customer. But the backend is nowhere near as good as shopify - you are copy-pasting addresses over to usps or ups, tracking orders with notes attached to stripe payments, and god forbid you should want to automate any transactional emails related to it. Oh, and your system falls apart when you start taking orders via ebay or etsy - since you linked so much process to stripe. So the whole thing devolves into a carefully crafted google sheet.

Which is all to say, i agree with the author - but i feel like we are winning the war, it’s just the battlefront moved from deploying backed services to gluing the pieces together.
