Hello, thank you for your positive opinion on my article, I consider very relevant your questions, if something we have shown as humanity is to go after new advances and, especially to achieve them, many optical instruments have been improved, and even replaced by new technologies, however, the practice of any old optical instrument is recorded in our history and will be there forever, no doubt, there will be people who will continue to use it and the youngest will adapt to new technologies, the important thing is to find the balance between each technological improvement.

The use of the sextant, for example, will always have the advantage that it will depend on the skills or abilities of the person who manipulates it, on the other hand an electronic device can present some failure and if the people on board in a certain boat do not have the ability to handle a sextant will have many hardships, hence the importance of balance between technological updates with those left behind.

I constantly come across students at university level who have forgotten how to solve elementary mathematical operations by the use of calculators, we can extrapolate this to the use of many other tools, such as the sextant, we must always learn to maintain a culture of teaching in balance and, in this way we will be forming our young people integrally and prepared to face in the best way any difficulty.

I hope I have contributed in a general way to the answers of your important questions, and thanks again for your visit to my post.
