GitHub getting on board legitimizes movement aimed at removing racially-charged language from software.
Technical debt is a concept in programming that reflects the extra development work that arises when code that is easy to implement in the short run is used instead of applying the best overall solution. Like the tale of the three little pigs, software is often written in order to be released as soon as possible, regardless of the medium and long-term implications of those decisions.
The speed of technology force us to research for innovation constantly: without an update and a daily training we lose our competitive edge. So we try new techniques, we learn new programming languagues which resolve our business problems more efficiently. But we must not lose focus, otherwise you could end up developing an admirable app for a colleague, but an poor solution for our clients.
