What is sixth generation in programming language?

Answer 1

There is no such thing. Until the introduction of third generation hardware, languages were never actually classified by generation. They were either low-level symbolic languages or high-level abstract languages and that hasn't changed to this day. The terms 3GL, 4GL and 5GL are nothing more than buzzwords adopted by the software industry for marketing purposes but they have no practical meaning as no such specification exists to define them.

Historically, the term 3GL arose after the introduction of third generation hardware. Thus all previous high-level languages became known as 2GL while assembler became 1GL. But it was all done reflexively as a result of market hype. Since then, we've seen 4GL and 5GL applied to programming languages but no-one can actually agree on what these terms really mean. They are marketing buzzwords, nothing more.

In some cases, 4GL and 5GL is nothing more than 3GL with some enhancement. In others, 4GL and 5GL are a completely new form of language altogether. Ultimately, comparing two 5GL languages is like comparing chalk with cheese. The term tells us nothing about the actual software.

Some attempts have been made to clearly define the difference between 4GL and 5GL. To some, a 4GL is a domain-specific language (DSL) while to others it is a subset of DSL. Meanwhile 5GL is generally regarded as being intended for Artificial Intelligence applications. However, just as with 1GL, these are merely reflexive definitions attempting to make sense of the meaningless. Unless the industry as a whole can formally agree upon what 6GL means, then it will be just as meaningless. All we can say for sure is that 6GL will follow 5GL. But that doesn't mean it is any better than 5GL, only that it is newer in some way.
