I suppose that's possible. My first "personal" PC had a "massive" hard drive of 1GB. My desktop now has 1TB. My first HD TV cost $1500,had a 34 inch screen and weighed 250 pounds. My recently purchased one cost $800,has a 49 inch screen,weighs about 40 pounds and features picture quality that's 20 times sharper than the first one.
Technological advancement proceeds at a dizzying pace.
The infamous “ they”, say that battery tech is progressing at 8%/year.
