When I bought a new 3rd generation (2010) Prius, the same FUD was going around. Articles I read said the battery would only last 10 years and then cost me $10,000 or $15,000 to replace. It was a lie.
I bought a used and abused 2nd generation (2005) Prius during the pandemic. Before 2019, I would not have offered more than $800 for the junker but in the middle of COVID I had to fork out $4,000 and it did need the battery replaced. Battery replacement cost me $1,400 in 2020 dollars, not $10,000, not $15,000 and this was for a car with even older battery tech than my 2010 Gen 3.
For me, electric cars make a lot of sense. I live in the Pacific NW where electricity is cheap. ICE cars pay $4.00 per gallon at 25 miles/gal, so $16.00 to go 100 miles. At home I pay $0.087 per kWh at 3.5 miles/kWh, so $2.50 to go 100 miles. There is minimal maintenance, basically adding windshield wiper fluid. ICE cars have oil changes, coolant, spark plugs, transmission fluid, timing belts, etc. EVs weighs a lot but only 200 pounds or so more than a mid-size SUV so tire wear is about the same. Sandy Monroe pointed out that the motors in the Tesla Model 3 is military grade and will probably last a million miles. Time will tell about the batteries, but based upon how things played out with the Prius and with laptop battery replacements, I'm feeling OK.
