I have some bad experiences with smart contract products. Not to mention news about wallet drain, exploits, bugs, etc is still common nowadays. I'd need more than just benefits to try them out. For example, verifiable smart contracts, multiple mechanisms to prevent remote attacks/phishing, etc. If it was not planned from the beginning, they need to test them with extra steps to make sure they don't miss anything. CMIIW.
Smart contracts are smart in a way that they can exploit your wallet and get more transaction fees from you and your wallets.
A more complicated a contract is, a more transaction fee you will have to pay, it's smart, and very efficiently for altcoin blockchain developers to get more money from their blockchain users. You interact more with their smart contracts, you pay more fees, they will get richer, you will get poorer.
Another example is from GameFi, Metaverse projects in the last bull run, in 2020 and 2021, many projects have total transaction fees from their users are bigger than their project market caps. Does it sound crazy?
Investors in those projects lost money, firstly here we only count in transaction fees, but they also have to pay money to buy NFTs, tokens and more items for playing, but at the end (not now but in 2021 or 2022 when GameFi, Metaverse projects started to plummet), market caps of projects are smaller than total transaction fees spent. It's very ridiculous.
