I've never invested in touchless technologies. Although perhaps I'm not understanding this as you intended; I've never invested in the stock of any such companies, though I have bought such products over the years.
I've long been sort of a squeamish person, even as a kid. I really didn't want to touch surfaces that showed a lot of fingerprints...that was the evidence presented to my squeamish tummy of other kids or adults doing rude things with their fingers and then touching the surface that I was now expected to touch... yuck!!
I'd always done things like use a paper towel to exit the door of public bathrooms, maybe used a knuckle or a pen on things like ATMs or pushbutton phones. I was really grossed out some years back when my bank installed an atm with a glass capacitive touch panel...all you did was touch, no button-pushing required. That surface was so disgusting and I would not touch it with my bare finger. lol, as they say.
And I suppose my Monk-like impulses have stood me in good stead over the years, and now in the pandemic days. ("Monk" is a reference to the television detective Monk who had multiple phobias of contracting things from surfaces and who was always cleaning.)
Now here are two "touchless" items people may not think of:
(1) I have installed a number of light switches throughout my home that sense when someone enters the room and then turn the lights on. And they stay on until the room is no longer occupied. This is greatly convenient. We walk through the house and the lights come on, and they go off a few minutes later. These switches are installed in the laundry room, several bathrooms, and a number of hallways and closets. This is really convenient, no fumbling for light switches in the dark (and have you ever looked closely at those switches? full of dirt and grime and crud!) These would not be good for a dedicated depression-era light-turner-outer like my sister, who turns on limited lights and they are turned off before leaving the room. However, with the extremely low power usage of LED bulbs any excess power usage is minimal. And, indeed, lighting technologies like incandescents, halogens, and fluorescents (and even LED) will suffer in terms of life span with increasing number of on-off cycles, so minimizing the cycling has energy relevance too.
(2) Long ago I had a speech-to-text software. The hardware was not quite there yet ("I...had...to...speak...like...a...robot..."). But nowadays this touchless technology is in my iPad, my Android phone, and so many other places. I use it with email, with messaging applications, and on my laptop. It's not perfect, I sometimes have to go back to edit a little bit and add punctuation. Still, it's really nice to have and use.
