So far I was fortunate that in most cases I am free to choose the tech stack for the products I make. I pay very little attention to "industry trends" (basically what FAANG tells us to do) and choose what works best for my business ROI wise.

As for developer pool - when I need to hire subcontractor I've never had problems finding one with enough qualifications in whatever area I would need. Btw all subcontractors I've ever had are remote since year 2000
