What NOT to start learning in the near future?

Question

Web development

I constantly meet questions like "what to teach a beginner in 2020?" etc. But no one wonders what exactly should not be taken on.
I would like to know what technologies have been widely used in web development for the past few years and now, but in 2-3 years they may cease to be used. For example, jQuery was very popular, but now (as I understand it) it is no longer comme il faut.

Answer 1

Everything except what is advised to teach on the topic: “What to teach a beginner in 2020?”

Answer 2

ActionScript and Flash in general

Answer 3

If instead of choosing "I'm interested in this and that, what is better to learn first?" the question is posed "what can not be taught so as not to strain the gyrus once again?", then the answer is obvious.
Your choice!

Answer 4

• HTML 4
  
• CSS 2
  
• ES5
  

Answer 5

What's the point in answering you? All the same, you won’t go further than the talking shop and you won’t learn anything. I've met enough people like you.

Answer 6

You are wrong about jQuery. The fact is that WordPress is on this lib and, moreover, on version 1.2 due to compatibility with older browsers. And now look at how many percent of the sites in general are on wp and you will immediately understand how many sites are on jquery unequivocally and how many more work on it once written.

Answer 7

Delphi

Answer 8

The story with Cobol in the states says that you need to learn basic things, and "add-ons" - as lucky, because:
"During this time, the front may completely change, a new promising backend may appear.
With this approach, you need to learn fundamental things and then, what they ask in vacancies.
