I've been developing professionally for 15 years and even in that short a time I've had to frequently start fresh in new frameworks or languages as the old ones lost their edge. The concept that someone would all-caps "NOT" use something is hilariously junior to me because the sands _will_ shift and you _will_ one day face the cliff of: my existing skills have no job demand, do I learn new skills or change profession? Harboring tribalism toward frameworks will not help you make the right decision in times like these.
