"I think, therefore I am" is not correct.
"I think, therefore a thought exists" is better.

[@tedgrant2]

"There is a thought" is even better.
"I think I am thinking" actually means "There is a thought, the subject of which is 'thinking'".

As Popeye said many times, I yam wot I yam an thas all wot I yam.
There is no concrete evidence of anything except my thoughts.
The evidence that you exist is very poor.

This is a visual media, not just an audio venue. Showing a picture of a painting is not my idea of a visual.

[@Ekvitarius]

The idea is to share audio through a medium where most people can find it.

[@PhatLvis]

It'd be a shame not to show the painting; Stallone had to sit for hours.
