At the end of 2009 I made two predictions for the next decade; Chinese and Indian developers having a major impact on the shape of code (ok, still waiting for this to happen), and scripting languages playing a significant role (got that one right, but then they were already playing a large role).
Since this blog has just entered its second decade, I will bring the next decade’s predictions forward a year.
I don’t see any new major customer ecosystems appearing. Ecosystems are the drivers of software development, and no new ecosystems has several consequences, including:
- No major new languages: Creating a language is a vanity endeavor. Vanity project can take off if they are in the right place at the right time. New ecosystems provide opportunities for new languages to become widely used by being in at the start and growing with the ecosystem. There is another opportunity locus; it is fashionable for companies that see themselves as thought-leaders to have their own language, e.g., Google, Apple, and Mozilla. Invent your language at the right time, while working for a thought-leader company and your language could become well-known enough to take-off.
I don’t see any major new ecosystems appearing and all the likely companies already have their own language.
Any new language also faces the problem of not having a large collection packages.
- Software will be more thoroughly tested: When an ecosystem is new, the incentives drive early and frequent releases (to build a customer base); software just has to be good enough. Once a product is established, companies can invest in addressing issues that customers find annoying, like faulty behavior; the incentive change results in more testing.
There are other forces at work around testing. Companies are experiencing some very expensive faults (testing may be expensive, but not testing may be more expensive) and automatic test generation is becoming commercially usable (i.e., the cost of some kinds of testing is decreasing).
The evolution of widely used languages.
- I think Fortran and C will have new features added, with relatively little fuss, and will quietly continue to be widely used (to the dismay of the fashionista).
There is a strong expectation that C++ and Java should continue to evolve:
- I expect the ISO C++ work to implode, because there are too many people pulling in too many directions. It makes sense for the gcc and llvm teams to cooperate in taking C++ in a direction that satisfies developers’ needs, rather than the needs of bored consultants. What are Microsoft’s views? They only have their own compiler for strategic reasons (they make little if any profit selling compilers, compilers are an unnecessary drain on management time; who cares what happens to the language).
- It is going to be interesting watching the impact of Oracle’s move to charging for runtimes. I have no idea what might happen to Java.
Moore’s law is now dead, which means researchers are going to have to look for completely new techniques for building logic gates. If photonic computers happen, then ternary notation may reappear again (it was used in at least one early Russian computer); I’m not holding my breath for this to occur.
