is Modifying Genes Impossible, or possible but very hard to accomplish?

Question

In this current moment, it's impossible to edit ur genes, u cant make yourself a natural blonde, or cure boldness, or get taller/shorter, or get green eyes, or straight hair, grow a new kidney to the damaged one... if you found a way to edit/modify genes all of those stuff would be possible... but you cant do it now....

so is my theory impossible, like cant be achieved or exist, or could it but needs very hard work and decades...

Note: there's a big difference between impossible and NEARLY impossible

It is possible under certain conditions, as with some genetic diseases where a very specific fault can be seen and the "undamaged" version is known.

A retrovirus can be used to edit the persons DNA and insert the correct sequence.

It's been in use since around 1990 but is still under development and by no means a routine treatment.

At the other extreme, as no one yet knows how to get humans to regenerate damaged organs, there is no way of changing genes / DNA to do that.
