[DC] If Clark Kent decided to quit being Superman and instead dedicate the same amount of time and effort into science and technology, how accomplished could he come? Could he compete with Luthor? And would Lex hate 'scientist Superman!' more or less than classic Supes?

Just realized that 'Clarke Tech' would actually be a pretty great name for a tech company headed by a super-genius (Clarke's Third Law and all that), so had to ask this.

Pretty damn accomplished.

Precisely how smart superman is varies a lot, but even at his dumbest he's very smart and has a solid grounding in the sciences. At his smartest, he's a literal supergenius.  Combined with his advanced kryptonian scientific knowledge, ability to rapidly research topics and supersenses able to see atoms- plus various superscientist allies should he ask for the help- he does indeed have the ability for Clarke Tech to rapidly become a rival to Lex Corp.

Lex would rapidly hate him as a rival. But if he learnt he was superman, or if he didn't bother to hide it? Lex would be beyond furious at him trying to beat him at his own game. He'd hate him even more.
