No, I would disagree. I like Tcl. I like using Tcl. The community is very good as well. The Tcl maintainers are really good at what they do for Tcl and the community.
There is no reason IMO for it to die at all.
Why do you like TCL more than any other language (ex. Python, Lisp, etc)?
Mind elaborating?
I can't think of one thing TCL does better than any of the languages that come after it that warrants keeping it around, outside of super easy C bindings and some light metaprogramming capability.
A lack of good resources on TCL also leads to people learning it all sorts of ways, and writing all sorts of (often buggy) code with it. Maybe that's just symptomatic of the companies at which I've used TCL, but I think it's pretty clear that there are way more good resources on something like lisp or python than there are on TCL (I mention lisp because if you squint and replace some [ ]s with ( )s, TCL looks almost like lisp)
A lot of my reasons aren't quite concrete, but in short, I think using an almost-dead language like TCL leads to stagnation of a code base. People aren't pushing boundaries, doing new things in TCL. There's definitely nothing wrong with having a no-surprises go-to language that just gets stuff done, but I just don't personally find TCL stimulating.
Maybe I'm just too much of a new-shiny-language hipster
I personally think it should die a very quick (honorable) death.
