I’m fairly sure a lot of places have to wait, unless you have an electric shower.
In the US people usually have an immersion heater tank for the hot water. Here in the UK I’ve got a combi boiler that produces water for hot taps, showers, and also central heating radiators.
In both cases there’s some distance of pipe between where your hot water is coming from and where your shower is and that’s what you are waiting for - for the water to get where it needs to go.
How does your stuff work?
Same thing happened with casette tapes and cassette mechanisms.
Most people think cassette tapes were terrible, because they remember the bargain basement iron tapes and no noise reduction. A top quality chrome casette when recorded well and played back on the right hardware is very difficult to tell apart from the digital original.
Similar story with VHS to be honest.
There’s a “minimum acceptable quality” which people were willing to tolerate, and manufacturers inevietably converge towards it in an effort to shave off a few cents here and there.
Audiophile now is very different, because it’s not a mass market consumer format any longer - it’s a niche hobby, and people are willing to pay top money for their hobbies.
