Originally very close to the machine, now computer programming languages take advantage of multiple layers of abstraction and make developers very productive.
Computer Languages
Various approaches that reflect the needs of the time are developed and adopted. Object oriented programming, integrated development environments, testing and deployment suits.
With time, through the decades, we’ve become able to produce computer code of increasing complexity and reliability, to the point that when major online platforms are unavailable today, it is worthy of prime time news.
Quantum computers will require a completely different approach and programming paradigm. AI systems will likely help in keeping developers productive, and possibly will be able to develop an intuitive understanding of quantum systems, which is beyond our reach.
