You are very kind. Thank you.

I do worry about the same thing. The Haskell ecosystem is very much geared towards experts and tinkerers (with laudable exceptions, such as, for example, the great work done by Chris Allen). Being an expert and tinkerer that didn’t worry me too much, but lately I am trying to make functional programming and Haskell accessible to a broader audience and it is an uphill battle. Even many professional software developers are put off even trying to install the toolchain. It is not that they wouldn’t been able to do it if they wanted. They just can’t be bothered because they are not convinced of the value of doing so at this stage — exactly as you are saying.
We should make it easier to get started, not harder.
