This reminds me of similar debate I had with one of my friends falling for NodeJS FOMO. The actual codebase was RoR and he wanted to go for Node for no apparent reason. I was able to talk him out of it but what I understood from discussion was peer pressure of “hey all of this could have been async”. While I admit blocking threads might not be permanent solution, they can still take you pretty far. Not to mention the folks wanted a MERN stack and I believe leaving Postgres for Mongo without a damn good reason is just crazy idea.
