For sure. I was just pointing this out because I've worked in organizations where there was no problem with delegating language choice to engineers but the minute any actual money had to be spent it was treated very differently.
You are absolutely right that technical decisions are economic ones.
Just want to point out, the choice to pick language X or language Y is very much about money. Training, triage, getting into production, scaling, testing, etc. Most bigger picture technical decisions are in fact, economic ones.
