I think this is possible. I'm surprised no one sees the real, stupendous cash flow monster. Nursing home care. Why people are not raving about the possibilities, I have no clue. Here's some numbers to work with, if a little rough.
"...About 1,290,000 Americans currently reside in nursing homes, according to the 2020 U.S. Census. That number is expected to nearly double by 2050.
Over 15,600 nursing home facilities are in operation, 69% of which are for-profit.
The average monthly cost of nursing home care in 2021 was $8,910 per month..."

$11,493,900,000 a month, $65,410,740,000 a year, $106,920 per person a year.
"...By 2060, 155 million Europeans
— 30% of the total population —
will be aged 65 or older..."
"...Persons 65 or older REQUIRING ASSISTANCE
WITH ADLS 44.4M...double today" [Activities of Daily Living (ADLs)]
So 22.2 million currently.

The link above suggest assisted home care from family to lower cost.
I suspect strongly that a Tesla robot combined with access to Tesla taxi service could dramatically cut cost AND make Tesla a huge whooping pile of money.
Most of what the robot would have to do is help move people around, wash, go to the toilet. I do not think with internet linkage to larger AI's, that it would not be impossible for it to cook.

I don't think it would be a stretch to say you could make and keep a Tesla robot for twice that, $16,902. The real cost would be much, much lower because it requires so much less in material cost.
$25,353 for Tesla robot and a Tesla model 3 (yes it's more likely they will use distributed taxis but just to get a number). Double that $50,706 or triple $76,059, and you still come way under the cost of nursing homes. The robot could be far more attentive and provide someone (or something) to talk to, and the taxi service could shuttle the elderly all over to make their quality of life much better.
At double, a profit of $37,865,370,000 a year just for the US. Add an equal number in Europe and you get $75,730,740,000. And this is all profit. The numbers would actually be much higher as I'm using full retail price. So the government saves a vast amount of money, people get individualized care and are allowed to stay in their homes.
And the number I quoted for a Tesla robot is tremendously inflated. I think I read the present processor in a Model 3 is $35. Let's say you add ten of these for more power. $350. Maybe $600 for all wiring, other semiconductors and power supply. 2,500W/h per day for batteries. At $132/kWh we have $330. Maybe $120 of plastic and aluminum. Comes to $1,400. You could surely build one for even less than this.
I wonder if this is not Musk long term plan. He never talked about Starlink, it was always, Mars, Mars, Mars, but as soon as he had the capability, he went full throttle Starlink. I think his robot plan is much the same. As soon as he saw he was close to the software stack and manufacturing capability needed, it’s now all, robot, robot.
The only question is why governments are not pouring tens or even hundreds of billions into finding ways to make this happen.
How I calculated the battery needs. Likely inflated, but should withstand worst case scenario. Maybe not perfect but something to work with.
"...Normal human metabolism produces heat at a basal metabolic rate of around 80 watts..." (Note: Heat not work.)
"...Over an 8-hour work shift, an average, healthy, well-fed and motivated manual laborer may sustain an output of around 75 watts of power...."
"...During a bicycle race, an elite cyclist can produce close to 400 watts of mechanical power over an hour and in short bursts over double that—1000 to 1100 watts.... An adult of good fitness is more likely to average between 50 and 150 watts for an hour of vigorous exercise. Athlete human performance peak power, but only for seconds, 2,000 Watts..."
For reference a good horse working at a good constant rate works at 746 Watts.
Let's say you need 400 watts for 2 hours a day then normal moving about at 100 Watts a hour with 7 hours for recharge at zero watts,
We need 2 x 400W/h + 17 x 100W/h = 800w/h + 1,700W/h = 2,500W/h per day
