I am personally quite torn about standardisation.
I always wonder what I would do if I created my own company. Would I mandate some popular language or would I allow every team choose whatever they wanted?
I can see a lot of good arguments in both sides and I have seen a lot of talks about the subject, and again, nobody agrees.
It is a little bit paradoxical what you say about the best tool for the job. I have similar experience and I see it as "the best tool within these limited and blessed toolset". When and how do you decide to add a new tool? It is really hard to quantify the value and cost, when we keep saying things like "more maintainable" or "easier to use".
Paul Graham essay is a classic, every developer should read it, not because of Lisp but to be aware of the Blub Paradox. It applies to all of us.
Out of curiosity, what language did your friends choose?
I guess for developers like you or me that love our craft, we want to get the most of our time, tooling and libraries. As such we like to have the best of the best, whatever it is.
That the promise of languages like lisp where you can easily build new abstractions that fit the best to solve the problem at hand.
But many things require several or many people either at the same time or over the years... maybe for example you'll not want to devote the next 20 year to the maintenance of the project you did in the past 5-10 years. This is where standardization make sense. If you get better productivity for yourself but the overall productivity drop, that a net loss.
So both aspects are to be taken into account. I would say in a big company, small independent team each completely responsible of its area even including the production make sense and help to scale that productivity. In today world, for many case, just saying your are able to provide VMs in the cloud that are able to respond to some kind of network queries should work and let of freedom in how things are done inside.
But even that doesn't solve everything. The interractions between teams will still dictate many things like what protocol data is exchanged. But also how you managed your database, what is overal architecture, what tools will you use for the continuous integration, QA testing, the cloud you'll use and how your application will skrink and scale dynamically...
There no much we can do alone in a big company if we don't cooperate.
I am convinced the language impact the productivity somewhat, but many other things impact it more. The programing language is a tactician choice, while the bigger things are strategist choices. And while you'll want to delegate the details to great tacticians, you'll want to have great strategists when you are in a big company... If just switching teams mean your employee need 6 months or 1 year before he become fluent in the technology stack, that's a real downside because this is only a small part of the job.
You are so much right. As Gerald Weinberg said:
"The Second Law of Consulting: No matter how it looks at first, it's always a people problem."
Thanks a lot for your toughts. It has been a pleasure to have a civilized discussion.
