Why is SPICE software so bad?

Engineer here with a bit of experience in the industry. I get that the software is robust but it's so ugly. LTSpice for example is clunky af to use and it looks ugly. It gets the job done but so much could be updated. Have asked other experienced people in the company what they think and their response is just that "it just works". Surely these can be made nicer. LTSpice, Multisim, Kicad all looks like they were made in the 90s, and scares beginners off.

A lot of professionals have been talking about AI as well. A few have been saying there's no way AI could be applied to electronics and a few have been saying that it might make some jobs redundant. Would be interested to hear what some of the professionals on here believe.

While the functionality is good, design is bad. Could use an update to make it fit within the current century.
