Seriously, a new guy joined out team and suddenly I'm out of my comfort zone and started following the pattern I used to follow. The thing he did, commented on my PR, a lot of comments.
I had this thing that hey now I can control anything right, new guy? less experienced? yes, so I don't need to be intimidated. But I realised today that I'm easily intimidated my intelligent people because I think now I am the inferior one.

I will push myself to think about it in a better way, by looking at it positively, to learn something from it.

My new manager is younger than me, really smart, and really competent. I am glad because I am learning from him. But his knowledge makes me wonder why I am not at his level coding wise. Frustrating.

If they're good comments then that's fantastic! Thorough PR comments are great. No need to feel intimidated, I regularly receive comments from juniors and I'm only ever glad they feel they can comment.

@AlmondSauce I wish my senior was like you...
Every comment is a direct attack to his ego and his will is the absolute truth...
He refuses to learn new technologies yet he gets always in your way when making new stuff..

@AlmondSauce Yeah I figured that I shouldn't be intimidated. So I have the sight but I realised that it was not a default behaviour for me.
Going through the comments, they are relevant.

@Grumm Seniors like that don't deserve to be seniors. You have to be unbelievably insecure to think you can't learn from anyone you deem "under you".

@Grumm I actually understand your senior, don't support it. I think I would have done the same if I am not being self aware.

I think it's more like your ego is hurt when you think it like someone who is you supposed be your junior criticises you(a detached term should be, gives opinions different than you), we think that we will be judged. In my case, I think my junior will lose respect and trust for me if he can openly criticise me. We try to save ourselves and this is being defensive.

When I talk to my senior, he always interested in understanding why am I thinking in a particular way, so always looks at my opinion as something to be considered if code needs to be good. He tries to objectively see the problem. I learnt this from him and today I tried to do the same, instead taking anything personally, I detached myself from my code and used the other person's opinions and instead of preferring anyone's I asked why one is better than the other.

@true-dev001 @true-dev001 Well imagine, you are making lists of sales manually in excel (copy data from one system, puts it in excel) start removing empty fields, change order.
Now I as a junior comes in and say, isn't it faster to create a query and use a pivot table to group and sort data.
What will your respons be ?
Mine will say : nope, I don't know sql it is faster I used to do it like this for 30 years...

How is that something about my ego ? All I try is making the tast faster and less manual than it was before.

@Grumm I understand why his ego is big and I am also saying that this behaviour is wrong. Your ego should not be an obstacle for your growth because in this case your senior won't learn anything.

Whatever you do, please, don't learn a lie

you (/everyone) is always inferior to someone.

i'd say it's better when that someone is in the same room as you, so that you can learn from them and use them to remind you of that simple unavoidable fact.
