I have. I would probably use my last phone for at least another year if it didn’t loose system updates. There’s too much important personal data (bank, photos, messages including medical info…) on the phone to risk using it unsupported. At least to me it is not worth it so I try to buy a phone with reasonably long support and buy a new one soon after the old one looses support.
Generally for extended periods you would pedal with something like 100 - 200 W while small electric compressors seem to be in > 1 kW region (and don’t get tired as quickly :D).
So basically with pedal power you could feasibly run some led lights and portable electronics but anything beyond this is not practical.
(Established) scientists have a long history of ignoring new theories not science itself. But that’s because at the end of the day scientists are still human.
Science is not great at working on a very short time scales. But give it enough time so more evidence is gathered and possibly some stubborn influential people (that can’t accept a new theory) die and generally we get closer and closer to truth.
It all depends on what is actually trying to be communicated. With your definition most meals would be plant based so why even bother to say it. With definition where plant based means no animal products it communicates that it is fine for vegans and it’s likely less offensive for people allergic to word “vegan”.

How far back does it count? Humans originate from Africa so everything we do can be seen as Africans doing things with stuff from all over the planet. Or perhaps even that is not far enough. What’s the origin of the first mammal… The only contestant is change and life is good at mixing things up.
To me many of the culture books start really slow/on the boring side but then they pick up and get really good. I really like how they often describe the culture not directly but through interaction with others.
