you have to put at least a little bit of context on asks like if you want a reply. Nobody knows how much water you use, how big of a house / apt, how many bathrooms, etc.
heat pumps just run something similar to a reverse Carnot cycle on their refrigerants and use a condenser coil to release the extra heat to the water. So for all practical purposes it heats the water inside the tank in a pretty similar fashion to how a normal electric water heater works, it just delivers it from a slightly different source and it isn't electric resistive.
So no, not possible. Theoretically you might be able to do it with a stupid enough system of coils and a very ridiculous amount of power, but it wouldn't be efficient or practical.
I'm still not sure why not possible. A tankless waterheater is just a regular water header with a tiny tank (pipes count as a tank...). I know electric tankless water heaters exists - they draw massive amounts of power (I considered one for my house, but it needs 4x 40 amp, 240 volt circuits - like most houses in the US I'm limited to 200 amps total and I suspect at times I'm using more than the remaining amount (not for long, but long enough to blow the main breaker)
To some extent ADHD drugs are abused but to us neurodivergent people those stimulants (or in other cases just alpha 2 agonists) just help us do normal things that normal people can do without drugs, like laundry. Or reading a book, or be able to focus on literally anything that isn’t giving us a high level dopamine response.
The meds (both stimulant and non stimulant) help people with ADHD choose where to hyperfocus, but hyperfocus is an internal trait of the ADHD neurotype, so it isn’t just attributable to the drugs or something.
I.e. normal people use stimulants to go fast, while ND people with ADHD use them to go slow or have their brain actually be able to slow down.
Spoken like a guy who has never had to maintain bare metal infrastructure ops at scale. These things break, need re-imaged, have parts that break, have to be configured (now you need provisioning pipelines, monitoring, alarms, etc), have to be maintained when something goes wrong (swapping hardware and software, debugging the alarms into actually figuring out which bits are broken and/or misconfigured), have to be catalogued, have to be planned for, deprecated, and the finances accounted for through complicated accounting to show investors the Capex at quarterly meetings.
Then you have to make fleet decisions on how much of each type of server you will want to buy, expanded storage, how long you will support each generation of server, when you will order new hardware, how to order new hardware, lag for real world installs, hiring actual humans to fly around to all of your datacenters and do the actual installations / maintainance / etc. Then you will have to do contracts with individual datacenter operators for margins, electricity rates, hosting contracts, white glove ops hourly rates, etc.
Businesses that own their own hardware tend to have a lot of employees whose jobs are maintaining it and running the business side of that.
Fraud that destroys market trust in a market that mostly deals in surveillance and selling intrusive data that was collected mostly unknowingly from the subject seems great to everyone who has any amount of integrity.
