Wasn’t CRISPR used to clone Dolly the sheep that had a very short lifespan? Aren’t there better editing techniques than it? Didn’t we learn that there seems to be a huge checksum in the DNA and if something changes somewhere, the checksum doesn’t add up and things go… well, dead.
No, CRISPR has little to do with Dolly the sheep. Dolly was born in 1996. While CRISPR saw some fundamental research from 1993-2005 it wasn’t used for gene editing untill 2012 and was named breakthrough of the year in 2015.
Dolly did not have a very short lifespan. She lived for six years and was eventually put down to a lung disease that has no connection to her cloning.
The wikipedia page has details and citations, I will only quote the relevant paragraph here:
Dolly lived at the Roslin Institute throughout her life and produced several lambs.[5] She was euthanized at the age of six years due to a progressive lung disease. No cause which linked the disease to her cloning was found.[6]
It is better to either do some basic research before making direct claims or ask more open questions. Stating wildly erroneous things is sowing disinformation, and putting a question mark at the end is not a very good loophole. You are actively spreading misinformation.

Dolly happened long before CRISPR was a thing.
No. An entirely different technique was used for Dolly.
