do people really care about boot time?

ive been using/managing/fixing computers and servers for 40+ years. from old AS400 to full on cloud bullshit. i can remember only a single time where boot time mattered... when microsofts DNS failures caused servers to take 15 minutes to boot.. other than that there hasnt been a single time it has ever been a problem or discussed as an issue to be resolved.

so why the fuck is it constantly touted as some benefit!? it grinds my gears when i see anyone stating how fast their machine booted.

am i alone in this?
