Would agree with this. I don't think the language choice, is as massive bet on the business as people think. I've seen much more niche and ancient langs without an ecosystem (no libraries, no SDK's to popular products, etc) build very profitable products. I would see these languages as a much greater risk.
As long as it has a base capability (libraries, maturity) and when people join they can be productive with it in a month or so then the risk is pretty low. For F# most .NET developers, even Node developers IMO will get used to F# relatively quickly. From my anecdotal experience with a number of languages its probably one of the easiest to onboard out of the FP langs balancing the FP methodology while trying to be practical/pragmatic. It has a large ecosystem via the .NET platform and supplements it with FP specific F# libraries where pragmatic to do so.
