Edit #1:
Thank you all for the comments. After sorting out some messes in my recent life and thinking things through. I do realize quitting isn't just a "magic bullet" to make world perfect. Still, it is good to read all of your posts and the solutions you guys offer!
TL;DR:
New starting Ph.D student in my very first year who has lost faith in my current university & my supervisor. Seriously considering quitting but don't know what to do.
Background
I'm 25 and have just graduated with a Master degree in computer science(computer vision, robotics specifically). My publication record is on track with 3 papers on A-tier conferences. I have good internship experience in the summer. Other than that, I have always had a great interest in research, machine learning in general, and I have been hardworking, from other's perspectives. I have a GPA 3.9 out of 4.0 for my master, and have been offered full financial support from my PhD program.
Current Academic Situation w/ My Supervisor
When I first applied to PhD programs, I applied to only two schools (my current university with my current supervisor & another good univ, both top 100) and ended up in the same university (I have also done my BS.c at the same university). While my current supervisor is a nice person & easy to talk to, I always feelextremely neglected & unsupervised the first thing. Most of the time, I only met up with my supervisor to seek research advice once per month or two only(I usually have to email him to ask beforehand so that he can coordinate a time, and sometimes he forgot still). However, for some engineering students, he will meet up way more often.
Secondly, every time I talked to my supervisor, I feel he's no longer interested in catching up to state-of-the-art compsci methods & prefer to work on more ECE-oriented projects on joint stick design or other things. This is also obvious, since all new students he recruited are from ece or mece & he's spending more time discussing with them. Another thing to denote here is that, although I'm working on computer vision research, there's no GPUs in our lab, and every time me or my fellow PhD student proposed for one he will sideline the entire conversation. This causes severe issue for me and my fellow PhD seniors, since we do not have the computational resource to demo any advanced Reinforcement Learning or Computer Vision methods on our lab robot, and we ended up settle with old GPU using our own money & have to make compromises in our methods(which renders our results weaker). However, he has no problem buying a 150, 000 fancy robot arm for the mece students he recruited.
Thirdly, after 4 years of observing my supervisor, I can fairly confirm that he rarely communicates with other professors in other universities (weak academic networking). I have talked to my seniors about this and they pretty much confirm this.
Basically, I feel I'm losing faith in my supervisor's capability in guiding me with a strong compsci resume for my PhD. While I totally agree that PhD students should be totally capable of conducting his own research, it doesn't make me feel less tiring and stressed over the fact that, I have to compete against top labs & univs for SOTA, and without constant feedbacks from my supervisor I sometimes feel very stressed and lost. The other problem is the academic networking, since my supervisor rarely networks himself, it has made it extremely difficult for me to get in contact with other leading researchers / experts. Another thing is the lack of investment in basic equipment (GPUs), where I sometimes felt my supervisor just didn't care.
Other Background
Financially I do not struggle for anything either, and I'm more than happy to pursue my PhD career, since I do love working research.
I come from a family of academics. My father is a professor in MECE with strong academic records & international connections (this is why I feel I'm struggling with my supervisor, since I have had a lot of experience with various researchers from my father's connections, and I feel my supervisor isn't catching up in years). My parents are well-aware of my supervisor and his lab situations(since I talk to them on a regular basis), and they always told me that it's OK and normal, as long as you work hard yourself.
I have talked to my post-doc senior, and my other PhD seniors (one of them has very strong publication at places like CVPR), they are all struggling for their own academic career compared to people coming from other top univs, or simply because the other people are more social with each other. I just feel my future is somehow hopeless even if I get a strong publication track and other thing (and that is a big if).
What would I do?
In summary, I am staying at the university where I graduate from my bachelor's degree. My supervisor has been making some peculiar choices & all my seniors have issues with their own academic tracks throughout the year. I feel my future is hopeless if I am to graduate from my PhD with what I have now. I want to quit my current university, and apply to a better place. I don't know if that's naïve since people get skeptical when you quit your PhD. I honestly have no idea what to do.
If I am to quit my current PhD, I'd need to apply for a work permit & look for a job since I'm not a Canadian citizen. I just feel clueless and feel something is missing from my PhD & am no longer satisfied of the situation I have to work with during my master. I'd love advice from anyone.
