On Line With a Commodore 64

This is typed with a Commodore 64 directly connected
to the Net. I wonder if our computer equipment is more powerful
than our needs require. If my C=64 can connect to
the Net & leave both a web page & a blog, then
any "dumb terminal" should have the same ability.
I compose all my hardcopy with the same computer connected to my
Epson 740 inkjet. What advantages would the latest
computer give me in this requirement?
If this capability were provided for third world
populations, education & productivity might be
improved.
If every student in the developed world were
given the equivalent of a C=64, education would change
at a very low cost.
We do not need what we are buying in many cases.
And we are throwing out "obsolete" computers
that aren't.
