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".

Language is interesting in this way. Same words in different contexts mean different things.
"Based on true events" = "Contains traces of what actually happened"
"Plant based" = "Does not contain animal products but can contain mushrooms even though they are not plants"
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.
There's also survivorship bias. All the crapily designed cars from 30-50 years ago are long scraped while some of the well designed ones are still around. With "current" cars you see the whole spectrum.
I guess the communities have to be of certain size to function and to feel welcoming to post into. For the first point you definitely need enough active users to make it feel alive but the second point is probably very person dependent. To me commenting in the big subreddits felt to much like showting in a very crowded space (so I didn't comment much) while currently on Lemmy they feel more comfortably sized and somehow more real.
Perhaps for the same reason I never really "got" twitter. I understand it's usefulness for journalists or celebrities but for me it was too close to screaming into the void to be useful/comfortable.
As for Reddit, many people will probably stick to it simply through the force of habit.
