It all started when futuristic technologists started to code 'Assembly'. This allowed them to build programs which they now wanted to run at tremendous speeds.
The arrival of 'FORTRAN', a higher level programming language brought along a new and faster way. In fact, Physicists still make use of it for applications such as astrophysical modelling of stars and galaxies, hydrodynamics codes, large scale molecular dynamics and electronic structure calculation codes.
After a few years, as soon as 'C' became accessible, everyone began to write their programs, declare their variables and manage their memory. Then 'Visual Basic' appeared and people found it to be a better way and proved handy to a lot of developers.
After a few more years, 'Lotus Notes' began to establish its presence as a heavyweight that created CGI programs that will run fast and deliver custom data to their very own http daemon. That was when 'HTML' came into the picture as a hard core programming tool.
If you are wondering which language to master in today's age of technology led disruption, then there isn't any right answer. Breakthroughs in AI / ML / NLP will lead to automation led software development even before we know it. The answer really depends on many factors including the kind of business you have, the kind of projects you would like to take up, the sort of resources you have at your disposal and much more.
The only thing that counts is if you can create or build a software solution which works well, fast and actually delights the client, then you my friend are a 'Solution Engineer'.
