Maybe it's just what I've been noticing, but I feel like Arduino was already losing its share of the hobbyist market. The plethora of small, cheap esp32 devices have already been taking Arduino's place.

    Same with raspberrypi really.
    companies just can't seem to know how to grow without line go up mentality.

    That's just it, you don't need to grow. Just sell a useful product at a reasonable price.

    In capitalism, the consumer isn't the target audience. A business exists to make money. The more money you make, the more shareholders you gain, the more the shareholders demand BLOOD!

    They seem to forget that "line go up" isn't the primary objective. If you make a good product and give half a shit about your customers, the line goes up as a natural consequence.

    companies just can't seem to know how to grow without line go up mentality.

    That's like saying "people just can't seem to harness the advantages of cancer without dying"

    If you never take money and get hooked by outside sources, you can just slowly grow, with no debt, beholden to no one

    If you take the money with any strings attached at all, you basically have to grow like cancer or your company will be sold for parts. It's inevitable at that point

    Don't take the money kids. If you have to take a business loan in the beginning - fine,

    was the comma a typo of a period, or did you have more to say here? if you have more to say i'm eager to listen

    I meant to delete the comment to keep things simple, but what I was going to say is something like

    fine, but debt is like gambling. There's situations where it makes sense, but it's addictive. It's mortgaging your own future, even when it maths out it's a risk - shit happens

    And if you over leverage and under perform, it's over. If you can pay yourself and your employees, you're better off never taking on debt again.

    Like Wegmans. It's the very best grocery store, everyone who goes there agrees. They grow slowly because they only open new locations when they have the cash to do so, and so they never have to compromise on quality in any way

    Odd that the newer RP2350 has a lower clock speed, while being improved in most other respects. Is that why the RP2040 is still seemingly the community preference?

    Personally, I never really counted the RP2350 as a successor. It's a different animal completely. A 2040 successor would be something like 4x cortex-m0's or a faster clock with more ram or whatever, the 2350 has completed different capabilities and components and can live along side the 2040.

    I feel like the preferred one is the 2040 simply because it's cheaper, and capable enough for the vast majority of use cases at this point.

    Edit: yes I know RPI called their board using the 2350 the pico 2, but the 2040 chip itself is used in more places than just the pico and not every one used the 2350 as a v2.

    Cheap. Also, a large part of the tinkering community never moves past soldering or perf board + lack of cheap 2354 boards. 2040 is already good enough for keebs and most projects. 2350 had eratta E9 published (gpio lockup) which killed its initial adoption rate for more advanced projects PicoLogicAnalyzer, protocol emulation, etc.

    I'm getting into meshtastic and learned how those esp32 devices are everywhere! They seem pretty neat

    Nice! I have a couple too. There's a community if your interested:

    Hey thanks! I was wondering what my alternatives were. Bought RPis, having remembered that name from a decade ago, and then read the posts here about how those are getting worse. Glad to see something that could take their place for my next project :) This is the kind of stuff I come to programming.dev for.

    But how many of those esp32s are programmed using the Arduino IDE and Arduino libraries?

    I love the ESP32, was onboard with the ESP-8266 (might have the numbers wrong, it was the predecessor), but I thought the real difference between the ESP-32 and the Rpi was that the Rpi has an OS with a possible desktop even (and all that Libux has to offer basically), as the ESP is more of a uProcessor you program in C/C++?

    Edit: Plesse disregard, I mixed up the posts and posted one levet too high too...
