Modula-2: what went wrong?

Hi,
    I was a big Modula-2 user from the days of Topspeed, through to
about 2001. We built simulation models (you can play with one here, if
you're interested:
http://bized.co.uk/virtual/economy/model/
- that's XDS Modula running
on Linux with a Java front end).

I haven't posted here in many years. The group was busier then!

I don't think we could have achieved anything like we did if we hadn't
switched to this family of languages (first Turbo Pascal, then Modula,
now I use Ada quite a lot (better sup****t, uglier language) whilst
former colleagues use Delphi(ditto) ).

So, I have two questions:

1) Why have these languages failed? Ada and Delphi are alive to an
extent, but none dominate, and - lets' face it Modula-2 is barely used
at all. At first sight, they offer so many advantages, especially in
clarity and type safety.

2) Is it fixable? Can anyone imagine a language in this tradition that
might be a hit? What would it look like?

I have my own views but would love to know what you all think.
