The great cycle.. lets not code too much ourselves, lets only be experts at our domain, lets use librarys. The librarys fail, they do not deliver the expected performance, they cant be customized or are suddenly not maintained and we can not port our whole ecosystem. Lets write most of our code ourselves, get independent from external actors, but we are slow now, glacial and distributed to reinvent a lot of wheels, while others outpace use in our domain. We should use more librarys.
