I think it's right to "scare" at least when you point out the places where we expect growth, i.e we expect exponential growth. You could say the Limits to grown (book) is about that it's an S curve and want people to take note and get ready for limits/brakes.

Some systems behave differently in a state of constant growth and in a resource limited state.

Knowing a curve will eventually level off isn't very reassuring if you don't know what level it will reach.

Sure it’s an S curve but we don’t know where it will level off.

This is the same as the response to people who bash economists for thinking “growth will go on forever.” Of course that can’t happen, but where is the top? Earth? Solar system? Galaxy? Parallel dimensions? Miniaturization and dematerialization causing extreme decoupling of economy from resource use? Nobody knows. The S curve could plateau in 10 years or 10,000 years.

I would have agreed with you. But think about it, when non tech people posed nonsense questions like "Do robots dream" we dismissed them because that is not how computers work.

Turns out they not only dream but they do it better than us! Maybe we can also rethink our then correct assumptions about the singularity
