On a more serious note,

> alias www='python -m SimpleHTTPServer 8000'

that'll only work on systems where python is python2

> alias speed='speedtest-cli --server 2406 --simple'

speedtest-cli automatically selects a server, invoking it without any opts at all is perfectly fine

> alias ipi='ipconfig getifaddr en0'

the interface name is not predictable, nor portable - `ip a`

Most if not all of these aliases seem rather pointless after all
