TL;DR Every day we use different technological tools, already on automatism, although we have not heard about them before. With the kn...

Tools won't make you "ultimate".

Like driving an F1 car won't make you the best driver.
Be critical of information that tells you the opposite.

Well, it's a matter of time. Compare a simple junior with Cursor and Senior with Notepad++, the code of the former is worse, but more tasks are done.

How did you measure that? And why even bother giving a senior a PC? Let him write on paper to show that your tool matters.

I haven't measured it. It's an empirical assumption. I want to write code on paper too 🕶

With no assumptions, if you compare apples to apples, there is still no evidence that productivity increases with assistance in the form of code generation.
Therefore, it's not even certain whether the same junior will experience an increase in real-world productivity (which includes code support/bug fixing time, or incident cost) with the cursor.

None of these tools will make you an "ultimate" developer. This is just the author's stack. The only way to become better is by learning.

Well, with such tools it will definitely be easier

None of these tools are a real gateway to "learn programming"

Tools can help making us ultimate but only if polish core skills in parallel to take best of both.

I made a small list. I hope it will be interesting to learn something new.

Important detail: Deno is not npm compatible in same way as Bun is. That makes transition from Nodejs to Bun easier (in many cases without any code changes).

Also, Buns' standard library has several useful features built in (worth checking out; it could save you from extra dependencies).

Bun is less stable than Nodejs, I encountered some bugs (it was a year ago, but obviously it's less mature then Nodejs).
