small nitpick, the x220 came out in mid/late 2011 and x230 in mid/late 2012, that's not 12 years ago.
And if you rightfully say "but 9 years is bad enough".. yes, but my x230 is only a little slower than my T460p and if I ignore the mobile Ryzens I don't see how a 2020 Lenovo T would be meaningfully better/faster than my 4 year old T460p.
