Its really outdated.

I'll say only one thing: HBTU is going forward with a good speed, but World is moving forward with hyper- accelerated motion. Remember Voyager 1 was sent in 1977, (search about it and) now think whats tech today. We can't even compare good institutes 50 years back with HBTU today.

All teacher are just getting their salary and thats all. No culture and environment.

No, there is nothing like that as the syllabus was revised in the year of 2013-2014. You can check the current syllabus out from the officials below -

Hope this helps!!!
