Regex: Match Characters After Multiple Underscores but not including Underscore

Question

I'm trying to get the first letter of every new word in the following string.

hello_world! hello___America! software-developer **for_life!?**

I've put together the following regex that almost gets there:

(\b\w|(?=)_[^_])

The problem is that it also copies the underscore preceding the next word.

See screenshot:

I want the letter after the underscore (or chain of underscores), plus the first letter of all of the other words that I already have highlighted with that regex pattern.

The answer I'm looking for should be abstract enough to capture letters/numbers/words split between one or more underscores.

Here's the Rubular shortlink

You may perhaps use a positive look-behind assertion ...

\b\w|(?<=_)[^_]
     ^^^^^^
