LOL the difference is that trash kids who pick cs for the money will burn out and be hardstuck senior dev even after 10 years of experience. The reality is that it's not the field but the person. You could be a legend in big 4 if you are good. If you suck then it won't matter where you go lol.

Also tech will always be relevant and there's no limit to it. AI, faster network, newer phone, tech, etc.

But that doesn't mean any moron can just study CS and even reach the GES survey salary average. There's a ton of mediocre NTU NUS kids earning 4k while the ones who actually enjoy coding are earning 7-8k
