That distinction of "flatly obvious" versus "obvious on a decade-only mid-range PC" seems to be pedantry. The parent comment doesn't say "flatly", for instance. In fact, it says "I find" which suggests personal experience, which would then mean that they weren't making a generalizable ("flatly obvious") claim.

Regardless, choosing the average consumer PC for your country (including the lower-class) is a much more reasonable benchmark than a high-end (your?) computer - and it seems more likely that tssge's machines (or mine) are representative of that average device than yours are.

I don't think that the statement was meant to be "bold" - it's pretty well-known that Electron performs extremely poorly on low-end devices, and the main reason why there's contention is because developers think that everyone has better computers than they actually do.
