The future of Angular is starting to look like: Signals, no RxJs (or much less), async / await, and ... NgRx Signal Store by
@ngrx_io
, which is going to play a crucial role in the signals era. A lot of signal-based Angular apps will likely use it. Agree or not, and why?

The myth is strong with this one ... 💣💥 YES,

You actually don't have to make all your asynchronous code use RxJs. RxJs is becoming optional in Angular, and many Angular projects already make minimal use of it.

This is what happens when companies get too big. The sales team takes over and end ups running the company. Product people are moved away from all decisions.
These are absolutely shameful predatory sales practices. "Sign a 120k yearly contract by the end of the week or else?"
