In terms of supply, Ethereum has unlimited supply.
In terms of security, Ethereum has inferior security compared to Bitcoin.
In terms of popularity, Bitcoin is known more than Ethereum.
In terms of price stability, Bitcoin is more stable, and Ethereum gained and lost almost 42% of its value in 3 months.
You shouldn't believe anyone who claims any crypto coin will surpass Bitcoin or even catch up to it in any field, whether it's an altcoin, meme coin, or shitcoin. The only coin that has surpassed Bitcoin is Monero, and only in security.
So no, I don't think Ethereum will ever catch up to Bitcoin.
Nobody knows what will happen in the far future whether Ethereum can level up with Bitcoin, but as of what is on ground and what we can speculate about their future, Bitcoin will always be ahead. In terms of security and popularity like you mentioned, Bitcoin is way ahead of Ethereum, also it's supply is finite and any experienced person in the crypto space should know this fact. The rate of popularity and adoption that Bitcoin is gathering around the world is geometrical, no other cryptocurrency is nearing it, so it'll be next to impossible for Ethereum or any other crypto to compete with Bitcoin.
