Using more powerful hardware as an excuse to make shitty software is incredibly flawed.
If newer hardware makes it cheaper and easier to make cool shit while maintaining the price point and power budgets of previous generations, who gives a shit?
This new stuff makes tinkering with hardware way more accessible than before and that is a good thing for everybody.
Arduino is excellent for what it was originally designed for - an easy, accessible platform for artists and non-engineers to experiment and prototype. Arduino are now reaching well beyond that market and targeting more serious applications, so we are entirely right to question whether a) Arduino's design trade-offs are acceptable in mass-market products and b) whether we really want to lower barriers to entry in this area.
Personally, I think the answers are a) no and b) absolutely not. If you need the hand-holding that Arduino offers, you have absolutely no right to ask a user to plug your widget into their network. Engineers are in a position of trust and we have a moral obligation to treat that position with absolute seriousness.
Their codebase would improve immensely if they used a more powerful chip to run Linux and Python instead.
