Why do you think C is the one true language? It's a tool.
There's a single very simple answer to "what tool should I use?". Use the best tool for the job
The job is the objective - what are you trying to accomplish? What are your priorities? What compromise is best between time, cost, and quality? What are your abilities? What's in your toolbox right now, and what could you obtain within the time frame?
For you, the best tool might always be C. I don't know how you've specialized or what you do, but C is powerful. Maybe you have an orderly thought process code meticulously, maybe you struggle to learn new languages. Maybe there's just no better option for the jobs you take on
For me, C is rarely the answer. Not never, but outside of school I can count on one hand how many times I've chosen it. I code intuitively and feel how the code fits together, I can pick up languages on the spot and switch even more easily. But I'm not meticulous, it's against my nature. I make mistakes frequently - but I learn by doing, and I don't need to understand to start doing
All that said, why do we keep making languages and frameworks? Because as programmers, we build the tools. We can also share them without losing them. The perfect tool for one job won't be the same for any other job, but a pretty good tool for many jobs is a valuable tool
The trade-off with our tools is between power, versatility, and cost (generally being time). We all want powerful and versatile tools - but our time is limited, and so we can't afford the cost
Ultimately, I think you've correctly spotted a recurring problem but misidentified the cause. The cause isn't the tools, it's the fact that the cost is someone else's time. And the fact we have no way to translate money into their time
A corporation can fund a team to continuously develop a tool they rely on. An individual can't - we could chip in a few bucks here and there, but we use a lot of tools. We don't know good tools from bad ones until we use them, we don't know what tools are used to build the ones we need either.
So everyone and their mom wants to build a service to fund work on their tools. I hate services, I don't want to give them my data or my money - I want tools that will work on my devices, not because I don't want to deny them pay for their work, but because I pick up, drop, and modify tools all the time
That's the real problem - if I could donate x dollars a month to support the tools I use, I would. If I could choose for us all to pay more taxes to support the tools we all use, I would take that deal. Hell, I'd go through the effort to generalize my personal tools
Instead, the only real profit to be had in OSS comes from companies, because they can afford to fund them directly, or services, which individuals tend to hate but companies barely notice. The tools aren't the problem - the economics are the problem
Motherfucker... How many times do you you have to fail before you listen to your customers, who are screaming what they want?
This is why voting with your wallet is nonsense. They'll never learn why they failed, only that they did
