It is no longer news that the world is evolving in quick succession leaving the obsolete for the novel (new) and that technological advancement, civilization and digitalisation is the era of the day now. By this, it requires thoughtful alignment with the present realities and guided decisions to determine the type of course to study and its relevance in the nearest future so as not to be left hanging. In the developed countries, some courses are no longer in vogue due to an upgrade of their educational policies to meet the current demand and realities while in the developing countries, this needs to be really addressed as many are graduating each year with no clear career path or progression based on their study of not-to-relevant courses in this present dispensation.
With the advent of technological advancement and digitalisation, some courses are no longer relevant in this present time as graduates of such courses many need a career change or struggle with such courses. The use of computers, artificial intelligence, remote job opportunities and unfavorable governmental policies especially in developing nations has rendered some courses irrelevant and may need to be phased out gradually or remodified to meet the current realities of things. More than ever before, there is a need for career/course choice guidiance, mentorship and going for the relevant. In no particular order, some of these courses includes but not limited to the following:
• Botany and Zoology
From my experience, many candidates who opted in for the "highly demanded courses" in sciences but which are not given are offered this courses with very insignificant few willingly going for it. These courses deals with study of plants and animals and is different from crop science or animal science offered in agricultural line which i found still more useful as food is a basic need of man. In developing countries, the job opportunities and career line of these courses are very limited and most graduates of these two courses that i know are now doing other things or opted for a change.
• Secretariat studies, local government administration and political science
These courses are good courses back then when the local government are still functioning well and when the governmental policies where fairer than it is now. For the secretariat studies, the use of typewriters, shorthands etc are now obsolete in this century with the advent of computers and powerful softwares in line with digitalisation.
• Sociology, anthropology and philosophy
Based on personal experience and observations, most graduates of these courses i know of are into other things as the glory days of these courses are gone. Most especially in the developing world, the relevance of such courses are dwindling day after day as the government isn't employing them into the civil service as before and very few got well paid jobs in private firms. Most have to divert into other things to meet ends meet.
• Library science
This was previously a course of choice when there were functional libraries in schools and those owned by government/private individuals. But now, with the advent of online book stores, softcopies coupled with poor reading culture nowadays together with decayed/poorly managed infrastructure to facilitate reading, choosing this course needs a special consideration before opting in.
The alternatives for such affected people is to change their career path to something more relevant in this present era. Of a truth, education (schooling) is a leverage anyone can have to see unlimited possibilities and not necessarily what one studies in school. I have seen people change career path even the so called desired courses like medicine, engineering, accountancy to other fields especially new fields as one desires. Therefore, literacy and also schooling is a leverage for as many that may tap into such. Also, entrepreneurship, learning softskills, volunteering etc are some things people affected may venture to even as they navigate. Also, for some whose courses are not totally obsolete, upskilling and certifications may be of help. In all, go for the relevant in course/career choice and not the obsolete.

Some professions will become obsolete, it’s inevitable and not a new phenomenon. This has always happened throughout history.
Exactly 💯👌
I agree with you
Change is the constant and inevitable, one must just learn to adapt and align.
Thanks for your comments
Thanks
You're welcome
Thanks
You see that library science I do not what people are studying in that course, is it how to manage the books in the library or the shelves because I am confused about this course.
It was a good course back then with core duties around what you mentioned above. There were few libraries then and governmental policies favours the library and book keeping then compared to now.
But now, times and season has changed.
