We are mostly (95%) a PHP company but going by trends; we did some projects in Python, NodeJS and Rails a few years ago.

Now I look back; I see the projects which have technical debt were flawed in design and did not get maintenance they needed. Most of them did not get traction to the point where scalability issue came into the picture.

So this year, we started moving that 5 % non-PHP projects to PHP counterparts. Again, we are miles away from any real-world scalability issue, but at least we are now able to maintain projects as we have a large PHP team.

At a small to mid-size organization level, it is more important to use one language for all projects.

I believe technical debt is not related to the choice of language but anticipating direction a project might take and picking up right design patterns to support that.

Which programming language is better is a highly overrated question!

I wish I had learned this few year ago.
