Hi G, it's been a while. Are you suggesting that we are already at a place where coding and programming are the drivers and not just the tools? While I would agree that we are headed there eventually, I would like to think that the faith of the independent trader has not been sealed just yet. Though, I've been a little out of touch with your part of the industry lately.
I would offer an alternative path with odds that are, IMO, in par with those of the guy who can actually afford MIT, Cornell or has done something so impressive so as to have the tab picked up for them.
Study math/stats in high school/college -> get a job related to your degree and be financially responsible -> trade on the side until you are relatively sure that you have alpha not luck -> push leverage to the max while such alpha exists. Clearly, it would probably take a little longer but an Ivy League school is simply out of reach for many.
I was more pointing out that out of the possible trading "jobs" there are plenty of options that are more lucrative, fulfilling and certain than trying to work at Goldman.
Almost nobody here as ever worked at an investment bank and the amount of ignorance about the entire trading industry is pretty astonishing.
To your other point, I think we've definitely made the shift to where technology is the driver rather than simply the enabler. All the firms I see struggling or failing are ones that have failed to invest in technology and they are being replaced by newer firms who are definitely relying much more on tech.
I've seen a few exceptions but not many. Manual trading is still possible and probably will be for a while yet but I wouldn't bank on it for someone going to school now and thinking that they'd make a career out of it. Plus, there's so much misinformation about how to go about it properly that the person would have to invest significant time figuring it out for himself. Anyone smart enough to do that should just use that time to learn to program instead.
