| Apr 22, 2016 at 18:08 | comment | added | Johannes Hahn | #3 is also false even if $\mathbb{F}$ is algebraically closed, because $\mathbb{F}[x]$ is a subring of $End(\mathbb{F}^\mathbb{N})$ via $x\mapsto$shift. | |

| Apr 22, 2016 at 18:04 | comment | added | Qiaochu Yuan | IIRC #2 is false and this came up on MO previously. (It's definitely false if the field is not algebraically closed but it's even possible to get a better dimension, I think.) | |
