fully concentrate on business logic...
How often have I read about cool new technologies where, after all, the programmer can now 'fully concentrate on the business logic'.
This meanwhile happens since at least 20 years so I wonder why still anybody does something else than concentrating on the 'business logic'?
One reason might be that it always has been a lie. Using any web framework still ends with tracking and analyzing HTTP requests or reading server logs, using persistence layers ends with monitoring the database, network traffic and such and so on. The promised abstraction just doesn't hold.
But - the main question is: Who - as a software developer - really wants to deal with business logic? Isn't business logic the most boring thing after all? What is the business logic of a webshop e.g.? Displaying a list, maybe filtered, putting things of that list onto another list (aka 'shopping cart'), sending an email, telling the backend. +1 here, -1 there. Nobody studied computer science for that. Business is all about lists and simple calculations. Let's face it: business logic is boring. Period.
I cannot imagine that our brightest minds cannot come up with a suitable solution for a shop in 20 years. Each year we have at least dozens of new-and-cool frameworks to solve that list-thing. +1. -1. Once again. How stupid.
Nevertheless programming computers can be exciting. That's why people try to get rid of doing business logic and do frameworks and technology. That's by far more appealing. Just to get that funded, they claim that later some poor guy can 'fully concentrate on the business logic'.
